I purchased a brand new GMC Sierra EV Denali from this shop. I got a great deal, great sales experience. I left a very happy customer. Two months and 4k miles later the traction battery failed while on a work trip 200 miles away from home. The dealer I was unfortunately towed to was AWFUL as they clearly had a malicious prejudice towards EVs (Stowasser GMC). Stowasser had my truck for about 3 months as they were unable or unwilling to run a complete diagnostics on a brand new GMC product. Stowasser was a nightmare. What's scary is that I didn't get my truck back until Sergio and Booke (from Costa Mesa GMC) stepped in to help me. Upon getting my truck back from Stowasser, I was discovered they did an incomplete job of replacing the traction battery as they did not bother to update the software even-though it was part of the job of replacing a traction battery. And I was ensured by the service manager at Stowasser that the software would be updated. Stowasser also returned may truck back with a daytime running light nonoperational. I was just glad to get my truck back with Brooke and Sergio's help. Brooke fit me in the day after I got my truck back and they got the daytime running light replaced along with updating the software and fixing the tonneau cover a few days later. Just in time for my next required work trip. 4k problem free miles later. I am only sad that I've moved out of Southern California, so I won't be able to go to Costa Mesa GMC for any needed service. Their EV techs are TOP OF THEIR GAME The service department really sells the next car. The service department at Costa Mesa GMC provided me with some of the best customer service (EV or NOT), even when my truck wasn't even in their shop!!!! From the shuttle drivers who dropped me off and picked me up. They really treat their employees well and it shows. Everyone cares! Pro-tip. If you rig breaks down and you find yourself at an awful dealer far from home, you can take use of GMC's reunite program. I wish I had known about it. If I had, I am sure the awesome crew at Costa Mesa GMC would have had me up and running within a few weeks and not MONTHS Stowasser left me brewing because of their political hate towards EVs! Thanks again Brooke, Sergio, the tech who fixed my truck, and the shuttle drivers. I would gladly make the trek and buy another truck from you just for the white glove service. My GMC Sierra EV is the BEST EV I've ever owned. It is the "cybertruck" Elon Musk should have built as it Out Cybers the Cyber "truck". Thanks again Costa Mesa GMC! I appreciate the empathy! 4k miles later and I am still problem free! read more

Bought a used car back in Oct 2025. The main sales guy was nice and wasn't a jerk which is surprising. I can also tell his hands were tired during our negotiation. We did go back and forth to get the price I wanted. He even brought his manager (South Asian tall leaner guy) who tried to come hard at me telling me the price is firm. I'm like this tactic is not only pathetic, but found out quick I don't play that. He's goofy. Anyway that's just part one of my many issues from this establishment ran by people thinking they're doing the right thing. My issues are also: The guy I was texting and made a schedule to meet never showed up and was handed to someone completely different. Disorganized. They sold me a car with 0 tank of gas Dusty inside and out - had to sanitize the whole thing myself Tire popped a month later costing me $500 to replace No record of any maintenance of the car at the car maker dealership Tires were already worn out and now spending $1.5k to get them replaced I will most definitely not be coming back here and will warn others. Disgusting how they did me like that. Brianna - Why do you comment on every bad review? You know nothing has changed. Just STOP! I can tell this has been going on for years. This establishment needs to clean house and have the new batch take several courses on how to provide good customer service 101. SO PATHETIC. read more

I feel taken advantage of and ripped off- I brought in my Cadillac for service, an oil leak and my transmission. I expressed exactly where and what it was one my engine I even showed him the leak. This place mis diagnosed my leak and reassured me my car was in good hands, kept my car for over a month. I had to rent a car to go to and from work. I rarely got an update on the progress or status of my Cadillac. I left messages with Cruz the service rep. I left messages with Sergio the Service Mgr. not one was returned until I went in myself to get an update. Finally I was told by Cruz my transmission was on back order not to worry. I then asked, "how's the oil leak repair going I know it is a major leak.(my oil leak was to the point it was literally dripping out from the second cam) and Cruz response was, "we have not started that yet because we are going to do it all together with the transmission." 1 more week passed and I got a call from Cruz telling me ,'Your car is ready all done," I returned his call and I asked wow how could that be if the transmission was on back order just last week?" Cruz- "we got it in the next day and we got everything done." (again no update on the progress) I picked up my car and the check engine light was still on! Mind you a Master mechanic supposedly passed my car off to me like this with the check engine light on. This was the biggest red flag that the mechanic or whomever the work did nit get done properly. Sergio the Service manager brought out his little apparatus and proceeded to attach the device to turn off the light. At that point I told him my car is not right, It still smells like its burning oil and I hear a strange noise. I even took him with me in my car to point it out. After driving he said, " take the car bring it back if anything goes wrong we guarantee our work." Here I am not even 2 months after with the oil leak present and I took it back to Costa Mesa Cadillac and I have been treated like I am an idiot. I have been disregarded and told this is a new leak coincidentally in the same area my cam. I asked Sergio to please honor the work and diagnosis his staff made that this is the same leak I originally came in for and he refuses to. I bring my car to Cadillac to avoid things like this and I will be following up with the BAR. read more

I'll own it: I'm a bit particular. Not "difficult," just the type who reads the fine print and expects the headline price to be the price. No test drive, no trade-in, no financing gymnastics--I wanted the advertised 24-month lease and to pay it in full. That should be "easy mode," right? Reader, it was not. If you've ever ordered a pizza online for $15 and had the driver show up asking for $25--plus a mandatory "anti-theft pizza lock"--that's basically my weekend at Costa Mesa GMC. The setup: Sunday around 10:30 a.m., I requested lease pricing for a 2025 Hummer EV. The GMC site showed a 24-month lease totaling ~$15,000. That was the starting line. Spoiler: we did a lot of laps. Communication? Like trying to text a brick. I had to call and follow up multiple times just to get a confirmation. At 12:45 p.m., I finally got a call: "It's about $25,000." No documentation. I pointed out that this wasn't even close to the website price and sent proof. Plot twist #1 (aka "The yo-yo"): At 1:56 p.m., the number magically became about $16,000. Progress! Then I asked for a written quote and spotted a stowaway: KARR security--5 years for $1,045. Not on the dealer site. Not on GMC's site. But apparently on my bill. Why this add-on felt especially wrong: This is a 2025 Hummer EV--a rolling supercomputer that already comes with built-in security features and OnStar/connected services. It's like being sold an "extra seatbelt" at the door of an airplane. The truck already has the safety net; charging another grand for a third-party alarm felt redundant at best and predatory at worst. I said "No, thanks." They said "No, actually." I asked to remove the add-on. The dealership refused because they'd "already taken a significant markdown to get to my price." Clarification: "my price" was the advertised price. "Apply online," they said. "But you still have to show up," they said. I completed the GMC online application around 6 p.m. Sunday. By 10 a.m. Monday, radio silence--then an email from the sales manager at 10:21 a.m. asking how they were doing. I replied quickly. No response. Plot twist #2 (aka "We lost your homework"): After more calls/emails/messages, at 11:30 a.m. I was told they don't receive the application from GMC and I needed to fill out a new one. I did--within minutes. Finally, a heartbeat: After several promised call-backs that I had to chase, I was told at 5:00 p.m. Monday that everything was processed and good. Pickup day, bring a book. I scheduled 12:30 p.m. Tuesday to sign and pick up, asked that everything be ready because I was short on time. I arrived 10 minutes early expecting crowds. There were none--not in GMC, not in Cadillac. A dealership tumbleweed moment. The Hummer? Not charged, not detailed. I waited another hour to even get into the signing office. Plot twist #3 (aka "Now you see five years, now you see three"): Once in the signing office, the $1,045 KARR "5-year" suddenly became a $1,000 "3-year" alarm. Still unwanted. Still unadvertised. Still mandatory. I asked to remove it--again told no, and that the earlier number was "priced wrong." And again--why that's absurd on a Hummer EV: Between factory theft-deterrent hardware and OnStar's connected capabilities (you know, the stuff built in so you can ping, lock, locate, and get help), selling me a bolt-on alarm felt like charging admission to use the door handle. The truck already speaks fluent "security." Credit where it's due: Abraham and Berenice were kind and tried to help. It felt like they were pushing a boulder uphill while the back office kept greasing the slope. The finale (cue confetti cannon that jams): I did get the vehicle I love--from a dealership I would not recommend to anyone. The "brand new" car had minor scratches, dents, and interior imperfections--like it spent the night wrestling a shopping cart. read more

I never write reviews. This is hands down the worst experience I have had back to back with two high end luxury vehicles here. Both a Cadillac and GMC. They put my family's life at risk and passed my new truck in a recall screening they set up and asked us to come in for. They passed us and told us it was safe. The truck has only 20,000 miles on it. Months later in the middle of a major highway with my two children in the car, the trucks engine failed mid-drive. Since then it has been a month of horrific treatment, horrible service by both this GMC, ownershop and Corporate. I have been in their "buyback" queue for a month, promising to refund me all my money and damage. In the meantime they could not even put me in a suitable loaner, then put me in a low level rental with barely anything and it was completely filthy when I picked it up. Now I am a month in and they wont cover the rental anymore they are claiming yet corporate has not completed the process. Sergio the service manager is among the foulest and least competent managers I have seen in any industry and I own multiple businesses. This is the most disgustingly dismissive "I do not care" kind of customer service at this dealership and I am telling all of you, from someone who has multiple cars from them, NEVER work with these people and NEVER EVER take your car to this service department. I hate reviews like this and like I said, you can look me up, I do not write them. This is the first time I have truly felt a business needs a reckoning and someone to call this out because this is beyond the worst experience I have had with a dealership in 30 years. This business should not continue to be able to serve the general public. They are passing off cars to be safe which could kill not only the occupants of the vehicle, but other innocent drivers as well. And then when that happens, they will pass the buck like they have been read more

On January 23 ,I dropped my truck off to have the breaks done .Made a appointment for Saturday service, they confirmed that I had a 8A.M. appointment. They informed at 4PM that my truck would not be ready until Monday at 10 A.M.,I picked my truck up at 10 ,they gave me $20 off for the inconvenience. I proceeded to drive off their property .After making 2 left turns on to Harbor Blvd., getting up to 40 MPH the left rear wheel fell off. They didn't put the lug nuts on, the tire proceeded across the medium and struck another car head on. Luckily no one was hurt .It's been over 9 weeks , I haven't got my truck back from them. You would think the last thing they would want is a Yelp review like this.No one calls to give me a status; just say they're waiting on parts . read more

Typical bait & switch by the team at Costa Mesa GMC. Attached AutoTrader photo shows their current advertised price. I called ahead of time to assure there wasn't a catch or added accessories required to purchase. There wasn't according to them. BUT, pricing had suddenly changed, and "auto trader is a 3rd party and they had it wrong,".... Then it changed to supposedly the pricing was expired from last week and not updated on the site. Somehow their pricing went up at the end of the month while their advertising "Black Friday" blowouts on their website. Be aware of this dealer. read more

Worse customer service ever, sales people are beyond disrespectful. Very rude people, not honest at all.

Well, my beautiful GMC terrain AT4 kept telling me I was due for oil service lol. I actually purchased my vehicle through Boulevard GMC in Long Beach, but decided to try out Costa Mesa GMC because it was closer to me. I'm glad I did! The service was five star from the initial phone call to schedule my appointment, to drop off and check in, to phone communication and pick up. Jessica in service was wonderful and they even washed my car before pick up! This is what you would expect from a great dealership with great customer service and I was thrilled. Ignore any of the wishy-washy reviews you may read and go here! Not only was the service five star but the place was impeccably, clean and service oriented! read more

Costa Mesa GMC - Car Dealers Near Me - Costa Mesa, California

Awful experience! We called as very serious out of state buyers for a 2025 Yukon Denali Ultimate and they pushed us off "stating they were too busy". They low balled our trade saying it's because of how different the CA used car market is compared to other states even though another dealer in CA offered us a reasonable amount similar to where we live. The initial salesman, Fonzi disappeared and we had to call multiple times to get answers basically just to get nowhere. The second Saleman, Erick just relayed useless information from the manager and said there was nothing they could do even after we had a standing pre-qual in their online system. Costa Mesa GMC made us feel unworthy and unwanted of our business. Absolutely shocked and appalled this is how we were treated after attempting to purchase a $100k+ SUV, especially after being loyal to the GMC brand for so many years. read more

Seems like a management problem... I filled out an online form requesting some info on a Yukon, litterally a week later I can't get the salesman to provide the info I want, what it the out the door price on the car, get asked for credit app, how he can help, but seriously can't provide basic information, I was attempting to "shop local" but major fail. Messaged another dealer, who miraculously was able to provide me what I asked in 15 minutes, and was able to wrap up the transaction and have car delivered within a few hours. Seruously, the insistence on trying to get the customer into the dealer is a major red flag, provide what's asked, it's certainly not like a freaking secret, and you would have had this deal. Total fail on a 90k suv, and quite frankly the reason people hate dealers. Also, despite telling the salesman that I bought it elsewhere and why, still get a daily message about wanting to help. read more

I personally regret doing business with this place. I recently purchased a 23 GMC from them last night came in with a Capital One approval and it took them two days to make the deal. The first time I went in they treated me like crap and acted like I wasn't buying when I was already preapproved. Then when I went back the very next day, they gave me the runaround made me run my credit to put another inquiry saying they could beat the rate I have and they could not!! Just put another ding on my credit not to mention the process took over four hours, just to process paperwork. They also would not give me a full tank of gas because they said it's a used vehicle and did not offer me two plates on my vehicle. I would not recommend this place and will never do business with them again be aware of their tactics they just give you the runaround if you don't know what you're doing. Don't listen to anything they say. There a waste of time. And don't deserve your money read more

Want to give a huge shout out to Kamyar for putting a deal on for me. Went Wednesday to set up a deal for my trade in but the numbers didnt really work out so i left. Mind you i live about 2 hours away from the dealership but they had the best price on a Canyon i had my eye on. Next day he called me to let me know he was able to move some numbers around and i got the deal i was looking for. As a courtesy, the new vehicle was delivered to my house and he drove back the trade, a 2 hour drive i didnt have to do again thank god. Great customer service, great salesman, huge thank you Kamyar! read more

I had my car serviced here and initially everything seemed fine. I paid in full and was told I needed to come back to have a part installed. That's where the problems began. Weeks went by and I never received a call back. After trying to reach out multiple times with no response, they finally contacted me nearly three weeks later. When I came in, I asked for photos of what was being installed--just to be clear on the work being done. My service advisor, Cruz ****, was rude and dismissive, telling me that if I didn't trust him, I could "go somewhere else." Not only did that comment come off as unprofessional, but it also completely destroyed any trust I had in the process. Overall, I felt unwelcome and disrespected. The lack of communication, accountability, and basic courtesy was incredibly disappointing. I won't be coming back, and I strongly recommend others think twice before trusting their vehicle with this dealership. read more

READ THE REVIEWS before you choose to spend your hard earned money on this establishment. I've been texting with a salesman from here for a little while now and was very upfront about what I could afford on a lease in a specific mentioned truck. The salesman advised me in order to get those figures, my manager would be more inclined to make it happen if you are here in person. I drove for two hours and asked for the salesman that was speaking to me. While the salesman gathered my name, zip etc. He came out with the figures, mind you, I had told him my budget was $600 a month, he came back at $1,000 plus monthly on same exact truck I had been texting him about. So, then the back and forth game ensued. I told him, I was very clear to you guys that I could not go over my budget. Then they came back at $699. Which was still $100 over my budget. So, I left. While I got on the road, the salesman called me and asked me if I could meet them at $657, to which I agreed. I sent in my credit application and had them run my credit etc. I came back to sign the wet signatures and the "Closer" came out and flat out told me, "I didn't know you were in the car business and that you pulled a fast one." Yes. The closer, whose job is really to capture everyone's business including whether or not the customer is in the car business blatantly said "you pulled a fast one." As if I fraudulently attempted to lease a vehicle from here. So, do yourselves a favor and avoid this dealer at all cost. If they treated someone in the business this poorly I can only imagine how they treat their day to day customers. read more

I had one of the most disappointing dealership experiences here. After a few days of negotiation with one rep that went nowhere, I was later contacted by someone else and gave it another shot. I laid out my terms clearly and professionally -- including a request to remove overpriced aftermarket add-ons and a reasonable discount on a high-mileage vehicle. After getting a vague text reply, I called directly to discuss. When I asked about the price, I was told, "The sale price is what it is." I then asked to speak to a manager and was told they were "too busy" because of the 4th of July weekend. That was the moment I decided to move on. Poor communication, no real interest in working with serious buyers, and a complete lack of follow-through. I won't be back -- and I'd recommend others think twice before wasting their time. read more

I drove 4 hours to purchase a vehicle (10/27/2025). I did the purchase online and got a price of $505 a month lease for 36 months and $4114 down. Rented a car 1 way. When I test drove the vehicle I told the sales person lets make sure the #'s are the same and we have a sale. Slam dunk and easy. Well when the finance/sales manager came over with #'s he told me it was going to be $771 a month with the same down payment. I showed him the purchase price on their company website. He compared all the numbers and when he verified everything his explanation was Dealer fees! What dealer fees goes up $266 a month and almost $9600 for the 36-month lease. I did not get an explanation. I was contacted by Jeremy (Sales Manager) the next day about my experience. Told him the situation and still have yet to hear back (2+ weeks later). I was contacted by Thomas (General Sales Manager), I also explained everything to him. I still have yet to hear from him too (1+ weeks). So, does this dealership really honor their prices or even have a customer service? read more

On May 10th, I sold my vehicle to Costa Mesa Cadillac/GMC. At the time of the transaction, I was promised that my existing loan would be paid off within 3 business days, and that I would receive a check for the equity difference shortly after. It has now been 17 days and not only has the loan not been paid off, but I am receiving collection calls from the finance company, and I'm now being forced to make another payment on a car that I no longer own. I've made repeated attempts to contact the dealership:    *   Left multiple voicemails for sales managers and general sales manger with no response    *   Used the website chat to request the General Manager's contact info -- was told they cannot provide it    *   Called the main line multiple times, each time told no manager is available This level of unresponsiveness and neglect of financial responsibility is completely unacceptable. I am hopeful that posting this review will get the attention of the General Manager and finally prompt someone to take ownership and resolve this issue immediately. read more

Beware* STARVED FOR CLIENTS SERVICE DEPARTMENT! I have been a GMC owner for years and have always taken my car to the service department in Long Beach although I live in Orange County, mainly because of the HORROR stories I've heard of this dealership. Against my BETTER JUDGEMENT I took my car to this service department due to a manufacturer recall on my car. Interestingly enough this recall was nothing more than a "SOFTWARE UPDATE RECALL" At the same time, my truck's lift gate stops working. The service attendant, Frank. Never stated that by just looking at my Lift Gate they would charge $300. To make matters worse there was ZERO LABOR performed on the car other than a software update?.. when I questioned the fee he stated that just looking at my car was $300 even if it was there for the recall and that the software update for the liftgate although it was nothing of our doing would explain the $300 fee? This just didn't sit well with me so I reached out to Sergio, the service manager whom with a very nasty attitude also stated that it was a different "SOFTWARE UPDATE" that damaged my Lift Gate and for them to look at it and perform the UPDATE was $300. This all just feels like a total rip off! Imagine if Apple or any other company charged you $300 or more every time they do a software update? Insane. We will probably sell this car and never buy GMC again. Also, if you really need a dealership or service department GO TO LONG BEACH. These people have such horrible reputation they're STARVED FOR CLIENTS and will take as much as they can from whoever makes the mistake to set foot in their door read more

I sold my 2021 Toyota Tacoma TRD Off-Road to Jose Martinez at this dealership. Why? Best offer for sure (so many lowball offers from everybody ... I got $6K more than what KBB spammed out to their network triggering an avalanche of irritating calls and texts from people asking me all the same questions over and over even though I submitted everything through KBB and then telling me I was crazy wanting more than the silly offers they were throwing at the wall) ... but my A+ experience with Jose is more than just the $$$. Jose was very responsive, professional, easy to communicate with, and made the process so easy. I even had to call back a couple times because I forgot to remove my Fastrak sticker as well as my HB City Beach Pass and he immediately went the extra mile to take care of these oversights. I highly recommend contacting Jose if you're looking to sell your vehicle and avoid all of the private party shenanigans (wasted time, scammers, payoff, DMV paperwork), lowball offers from brokers and sled lots etc. If your time is worth money, then don't waste another second. Last comment, DO NOT list your vehicle on Autotrader that is a total waste of $78 (don't ge me started on that one, just know the old days of the newspaper printed version are long gone and whatever remains will do nothing to help sell your vehicle ... and Tacomas don't sit around collecting dust here in SoCal mine was a real gem too).

Costa Mesa GMC - My baby! Needed a mobile office setup so bought a Sienna - Car Dealers Near Me - Costa Mesa, California

See all

It was the most terrible experience I've ever encountered. I bought a 2024 GMC 2500 Denali Ultimate for $115,000 with plans to travel the country towing my new 2023 Airstream Classic. Unfortunately, problems arose when the truck's trailer brakes repeatedly malfunctioned while towing. After several incidents, I found myself going back and forth between the Airstream and GMC dealerships. Eventually, I sold the Airstream six months later because the brakes kept disconnecting without warning, making it impossible to stop safely and being repeatedly told by GMC it was my trailer. Even though Airstream told me it was my truck. I then purchased a new 2024 DRV 5th wheel to ensure reliable braking and avoid dangerous situations while driving my RV. However, during a trip home with the new RV, the brakes disconnected again about 400 miles in as I was descending a long hill with an 18,000-pound trailer. This was extremely frightening and hazardous due to the trailer's size and weight. Luckily we were able to make it to a safe location. We immediately visited the GMC dealership, who claimed the problem was with the trailer yet again. Weeks later, we received a letter from GM about a recall addressing the issue of trailer brakes disconnecting while driving--a problem experienced by many other trucks based on several blogs we came across when searching the internet. I took the truck in for the recall fix promptly. After it was supposedly fixed, we set off again, but 20 miles into our trip, the brakes failed once more on a steep, two-lane road. We ended up in oncoming traffic--it was terrifying, and we barely managed to stop, disconnect the trailer, and head directly to the dealership that had done the repair. I was extremely upset. The dealership suggested pursuing a lemon law claim with GM. I spent a month on the claim, but GM denied it without providing a clear reason, only a brief phone call. I assumed they were trying to avoid liability by not giving any documentation. Frustrated, I reached out to the dealership about my situation, as I had a new truck but couldn't safely tow my RV, leaving me stuck in an RV lot. The dealership informed me they'd coordinate with a GM representative to explore the next steps. I returned the truck for the sixth or seventh time, leaving it for a week. Today, they notified me the truck was ready and concluded again the issue was with the trailer, not the truck. Even though this was my second trailer with the same issue. I was taken aback by their conclusion, especially since GM engineers had inspected it a second time. My dissatisfaction was evident, but the service manager, Sergio, took offense and told me not to return to the dealership. I bought this $115,000 truck specifically for towing, but the trailer brakes constantly fail so we are unable to utilize it for the reason we purchased it. I am utterly shocked by the entire experience. If you're considering purchasing here, beware--they may tell you what you want to hear until you make the purchase, but if something goes wrong and there's a recall or you experience any problems, you're on your own. read more

For other's awareness: the add-ons they sell you at signing are NOT required, even though the financial person tells you they are. That's a lie. I opted for a separate tire protection plan (Ally), but they also added "Nitro Fill" that does the same exact thing, but with less coverage. I asked if this stuff is required and they are allowed to say yes, even though it is not true. You can tell them to take stuff off - I didn't know that at the time. Once I read over the contracts of the stuff they said are required, they all have a clause that says you can cancel within 60 days for your money back. I email the Nitrofill company and they say the dealership has to do the paperwork to refund you. So they are kind enough to forward the request to "Anthony". After 3-4 weeks asking for a status update, Nitrofill calls them and Anthony says he's not the person that does that, it's Leo (finance lead?). Another few weeks later and this Leo person has not sent any update either. No contact or communication what so ever from this dealership team. They make money off of selling these add ons and it's quite ironic how obvious they make it that they don't want to refund it because it's money out of their pocket. I advise everyone to steer clear of doing business or, if you must, tell them directly to remove all the add-ons they try to slap on and say are required. None of that is. If they push you, walk out and don't look back. They'll fold and sweet talk you into saying they're doing you a favor in removing them. It's all BS so they make an extra buck. Attached the email thread as proof of how annoying this entire process has been. Incredibly unprofessional and shows how little they care after they take your money. TLDR: Submitted a request to cancel an add on they said was required, but legally is not. It has been 6 weeks since then without a single update and still no word from anyone. read more

Do NOT go to this GMC. My husband and I were looking at a USED GMC truck and the first night we went, they had us speak to someone that only spoke English AFTER I requested someone who speaks Spanish, we just saw it and then over the span of a week, they still had us coming to dealership from an hour and a half away and they couldn't give us a straight forward answer as to a bank approval or not- the customer service was HORRIBLE, from all the associates here except for one, sweet employee, Natasha. read more

We had a great experience at Costa Mesa GMC purchasing a used vehicle through Nick Torres. We came on a Saturday and were promptly greeted by the team and offered a test ride. Nick was super friendly and helpful throughout. The whole process went really smoothly with the entire team, and we picked up the car the next day fully detailed and charged. Thank you Costa Mesa GMC. read more

Absolute Scam Artists! These people have zero respect for other people's time. I came in to inquire about a vehicle and they took my keys and registration and tried to hold them hostage to keep me in the dealership. It took them two days to get back to me about a final price of a vehicle. I came in to buy a vehicle at a price we both had agreed upon. While in the financial office they tried to raise the price last minute because of their mistake and would not honor the original price agreed upon. I had to even try and negotiate with them to fix a crack on a vehicle they were trying to sell me. Do not send anyone you love or care about to buy a vehicle at Costa Mesa GMC. Zero Integrity. read more

This is a sad review to post. We purchased 3 cars from this dealership in 2021 and 2022 and referred family members that also purchased cars. We felt like they cared about us. The service was awesome, they were confident in their product. We felt like family. Ownership has changed and it's incredible how in so little time the entire culture has changed. High turnover in people. Service time and delivery is a disaster. Salespeople are not very knowledgeable. After such a positive experience to determine we will take our business elsewhere is sad to admit. It's gotten that bad. We miss you Suburban GMC. read more
