Service department was excellent Nobu was great he was very helpful. I was in and out pretty quick all work was completed in a timely manner. read more

I have been coming to this dealership for more than 20 years to bring my car for service and I have always experienced friendly and professional staff. Thank you to Chelsey for helping me during my last oil change service. It was completed in a timely manner and they also took the time to wash and returned my car nice and clean. read more

Service there is fantastic!!! Second to none. Keep up the good work. The whole service team was helpful, respectful and courteous.

I took my suv to get serviced Dario Gomez helped me and kept constant communication. He was thorough and very kind. The waiting area was clean. It was overall a great experience. I recommend Dario and this service center to everyone! read more

Had a great experience with the service department. Everything done in a timely manner, staff was very welcoming and helpful.

My experience with Mark Christopher Chevrolet is less than 1 star. We purchased a new vehicle from them & was promised floor mats. After several inquiries with nothing but excuses we gave up. In 2023 we purchased a used vehicle. We paid $36,000.00 cash I might add. The engine had to be rebuilt ($12,000.00) in less than 30 days of the purchase. I felt that they should have covered atleast some if not all that expense. They gave us a $100.00 gas card. Caveat Emptor!!! read more

Took my car in for service, customer service was great, friendly staff, and reasonable prices! I'll definitely keep coming back !!!

I don't leave reviews often, but considering the amazing customer service I received from Jeff, I had to let it be known. I've never felt more comfortable at a dealership. He was kind, honest, and felt like he was on my side. Everything was done in a timely manner and I will definitely be recommending him to anyone. read more

Brought my 2024 CT5 for service unscheduled. Unsure if I would be able to receive service before a last minute family trip. Dario came to my rescue! He was prompt, efficient, and got me back on the road in record time. Thank you Dario and Mark Christopher Cadillac. You have earned a life long customer! read more

This was the worse experience . We brought our old Denali in for the cash offer from KBB . Joel from the dealership was who we communicated with and when we went in to drop off the car he wasn't in . There wasn't a mechanic on site to do any type of evaluation so we were going to return on a weekday. Monday he reaches out and tells me he's going to give us 700 instead of the 3100 that Kelley blue book had offered. He never looked at the car. He said he could run the analytics without us even being there and I'm trying to figure out why they didn't offer this when we were there Saturday so now we have to drive all the way back just to have them give us a check for $700 because they said they couldn't sell the car for much more than that. I think it's more of a cat and mouse game and it seems more like a scammed than anything, very frustrated and upset with the whole process. read more

Yeah so I seriously wish I could leave negative stars. I've walked in to pick up my part and I've been fully ignored for like 5 minutes now. No hellos or anything. When I just got helped I was told because it's an accessory that he can't help me and I have to wait for Ruben, the same guy who sent me the email then forgot he sent me the email, and now I'm back to being ignored. I will NEVER come back here ever!! read more

I am one who normally doesn't write reviews however I had the most amazing experience and had to. I took my car in a few days ago to get serviced and was greeted by a service advisor named Nobu. He was extremely polite and very welcoming. As I had some questions about the issues I was having with my vehicle a service technician named Brad O came out and he was beyond helpful and answered every question I had! I have taken my car to other places and always feel like they give me the run around and never truly help. I can honestly say this was the best experience I have had and would highly recommend everyone to come to mark christopher for services! read more

Took my Cadillac in for service and couldn't be happier! Everyone was so helpful and the part that needed replaced was done in a timely manner! I didn't expect to get my car back so quickly. I won't go anywhere else now. read more

I brought my 2018 CTS in for routine service. I was greeted by Chelsea who was very professional and kind. She told me about 2 1/2 hours for my service and it was done in 2. Chelsea made sure to let me know of a few things my vehicle will be needing in the near future. My vehicle was already parked out front and washed for me after I paid. The experience was exceptional. I will definitely be returning here for any services my vehicle may need. read more

I have been bringing my Cadillac CT5 to Mark Christopher to get maintained for a while now. I met Chelsea in the service drive recently and she took the best care of me! She made sure all my concerns were addressed and now my car is running better than ever. The service I received there was phenomenal! read more

I dropped my Cadillac Escalade for my one year maintenance and am thoroughly impressed by your service department. Nobu greeted me upon arrival and informed me of the process and had a loaner Escalade immediately available for me to drive. No hassle-and super easy. It's unusual to be treated with such respect and care AFTER a sale...I felt like a VIP! I will definitely bring all of my GM owned vehicles back to MARK CHRISTOPHER for service in the future. Thank you Nobu for the follow up and all of your patience with me too! I appreciate you. read more

Received a 0 star service from sale guy Rami Mahroom. This guy has no knowledge of the cars, spoke full of lie. Avoid at any cost, run away!

My husband and I are very happy with our purchase. Rami greeted us from the beginning and was incredibly helpful. He helped us look at the vehicles and we test drove the vehicle we liked. Once we decided on our purchase, Ray helped us with the financing and closing the deal. Larry finalized the details and we were set. Thank you to Rami, Ray, and Larry for making this important purchase easy and hassle free. I highly recommend Mark Christopher Auto Center for your next car purchase. We will definitely be back. read more

Purchased a $135k Escalade. Bumper is falling off and speaker is busted. Notified but still no resolve.

Wow, my previous experience here was amazing. This time not so much. Dropped car off on Tuesday and they did not even look at it until pressed for an update the following day because they were busy. I made an appointment so my car should have been expected and looked at Tuesday but they got to it end of day Wednesday. I was charged $235 for a diagnostic, that is a scanner tool hooked up to tell you the issue. $235 for labor? Shame on you. We came to your dealership trusting value and expertise. Will never make that same mistake. Better business bureau next. read more

I'm always happy coming here for oil changes,they never let me down, except for one time when they cancelled my oil change appointment; that was unexpected I didn't know it could happen I was blindsided took it elsewhere because light was on, I didn't make a fuss about it, I'm hoping it never happens again. read more

See all

Had scheduled maintenance at 1030 left car said they would call/text when car was ready. They didn't. I called at 1530 to see if car was done. Was told to pick up at 1630. Told they were filling w oil. Husband had asked for wash as well. Was told it would take 30 mins. Opted for no wash. Was made to wait 30 min anyway. Was told I had a non repairable leak on tire however I took care of it to tire place willing to buy a new tire and was told tire was repairable and no need to purchase new tire! read more

Cadillac dealership does an OK job. There is nothing that stands out, nothing to wow you for spending $150k on an SUV. Same level of service and treatment as any other car. There are not many Cadillac dealerships near by so your almost stuck. read more

The service wasn't good , I had to pay for my car to be fix and they didn't fix anything so I still have the same problem with my car

Just bought a new Buick 2022 at Mark Christopher and had a great experience with Alex Sarabia as our sales person. Alex could not have done a better job. Great experience all around. read more

STAY AWAY FROM THIS DEALERSHIP AT ALL COST!!!!! I wish there was a way to give Negative stars, because this is what this dealership deserves. Twice now I have taken my 2017 Cadillac CT6 Plug-in into this dealership and twice they have lied to me and flat out been deceptive. I should have known after the first trip there, but because they are close to my work I decided to give them a second chance. Man was that a HUGE mistake. I have owned my car since new, and have driven it over 65,000 miles. I am also a former Sales Manager at a GM dealership here in So Cal that sold Cadillacs. So I know these cars inside and out. Therefore, I think I pretty much know when something is not right. Twice now I have taken my car into this dealership and explained to them that the transmission has been extremely rough and producing a violent jerking while accelerating and braking. I even took the technician on a test ride so he could experience what I was talking about. On the test ride the technician acknowledged hearing and feeling the anomaly and said he would need to keep the vehicle an extra day so he could inspect the transmission to find the issue. The next day I get a call from the Service Advisor Sandra S., telling me that what I was experiencing was NORMAL, and that it was caused by accelerating too hard. I replied that I have driver this car 65,000 miles since new and that it has recently started doing it. And that if the issue was caused by hard acceleration, how do you explain when it happens during braking. She insisted in trying to tell me I was wrong and that it was normal. When I told her I think I have driven and sold enough of these cars to know it is normal, AND the technician I drove with also realized there was a problem, she sarcastically said, "Well what do you want us to do?". I asked her, "Basically your telling me you aren't going to fix it?" and she just said, "yes." So I go pick up my vehicle and read the report of the technician. It was a complete and total LIE. He listed that the vehicle only produced the issue on Hard Acceleration, that it was normal when the transfer of power was being made from the electric motor to the gas motor, and that the sensation of violent jerking was caused by the wheels spinning and breaking traction with the ground. Anyone who has driven the Cadillac CT6 Plug-in knows that you can press the accelerator to the floor and the wheels will not spin. The technician totally lied and listed that there was nothing wrong with the vehicle. Even after taking a test drive with me and agreeing there was an issue. Now I have to take it to another dealership because sometimes the violent jerking during braking is so bad it is dangerous. Hoping this doesn't cause an accident. Because believe me, my attorney's will be giving a call to Mark Christopher Cadillac if that happens. There complete failure and lack of transparency has put me driving this vehicle in danger. I would have had more respect for this dealership if they simply said we just can't find it, or perhaps you should take it some where with more experience. But to try and tell me it is normal, and then lie and be completely rude and unemphatic to my issue is absolutely unacceptable. This dealership is deceptive, lying, and uncaring. I would avoid them at all cost. I am ashamed that there is a GM Dealership like this. I worked for and sold this brand for years, and my dealership would have NEVER treated a customer like this. - read more

Oh boy how I can I say I was amazed today! I came to this oasis and my mind was blown away! First I came in with my expectations and my guards up it's from stereotypes given from to car salesman. But it wasn't the case here my man with the plan Chris Cuevas took my wants and needs worked hard to fulfill them and knocked my socks off! He delivered a package with everything I wanted and needed I fell in love the car and Larry in finance worked with me and offers a deal that I couldn't refuse! I'm so happy how everything worked out my life has changed for the better and I'm comfortable with the process of how everything was handled like professionals!I've never trusted a person more with my overview of final process. The manager Ray was there to reassure I was getting the best deal mark Christopher Cadillac can offer! This outstanding team fought for me and made my dream come true! I highly recommend giving this dealership a shot if you're looking for car of your dreams because I experienced it first hand they can make it happen without any sacrifices! All I can say is thank you Chris, Larry, Ray! You've made me feel like I won the lottery and hit the jackpot! read more

My wife is looking to change over to the Cadillac family. That decision was abruptly shattered by Mark Christopher Cadillac. First, there was almost no inventory, the salesman did not know his product and when he showed us a model, this is what he showed us; If this is the quality of the GM, major changes need to happen now! read more

I purchased a Cadillac XT4. My experience was pretty good. I'm always leary when car shopping but the guys at Mark Chris made it painless. They were professional, kind and patient as I made my decision and they weren't pushy. I especially appreciated my sales rep Jose(on the Cadillac lot) he was great! Definitely go see him. He will take good care of you. read more

Jonathan Villa was literally the best guy to work with. We really enjoyed our car buying experience with him. He's extremely knowledgeable, professional, and ultimately kind. He answered any and all questions with ease and accommodated any concerns. We didn't feel rushed or like a bother at all. I would highly, highly recommend working with him on your next purchase.

We'll definitely be coming to you for any future purchases!!! read more

I called on Friday 7/14/23 and spoke to Omar about a 2023 Cadillac a CT5 I had seen on the internet for 36k with 2miles. He appeared to be interested and checked to see if it was still available it wasn't, but said they had an other one exactly the same. He requested the information for the trade I had informed we were interested in using as a trade and I sent the requested information, vin , year, model, etc. He said he would call back with some numbers or disposition and that was the last I heard from him? The purpose of this review is to let management know that sales could be lower than expectations, perhaps someone is dropping the ball. We were potentially ready to buy , but not with that type of customer service! read more

Just reported this dealership to GM Motors and they are thankfully forming a case against them and helping us. I am just bummed I didn't do it this way, to begin with! Thanks to Costa Mesa Cadillac for giving us the info on how to report them. They sold us a car they never fulfilled a package on and the managers have ignored us for 1.5 years and never sent the package. We have receipts and recorded calls. Thankful we are finally getting help and other dealerships have helped. Owned an Escalade for decades and always had good service besides this dealer. The man who answered the phone this morning in sales was so sarcastic and rude when I explained our story so I went straight to GM. Shame on them. The other reviewers show the same. read more

Took my vehicle in to be fixed. It took two weeks for them to order the part. They sent an email stating my vehicle was ready. They never stated that if I wasn't there at a certain time I couldn't pick up my vehicle cause no one would have access to bring it out. I had to wait 3 more days since it was Thanksgiving weekend. No courtesy wash. I received it back filthy. Just plain poor service with no communication. Definitely would not recommend. read more

Subpar service center People were nice but as far as service goes I was super disappointed. I got an oil change, they don't accept my maintenance package that was purchased with the vehicle. I've never had an issue with that at any other dealerships including dealerships other than the one I bought the car from. Also at all other dealerships they offer a complimentary wash & vacuum... They do not do any of that here. read more

Brought cadi srx in June for safety recall. Service was done in one day with appointment. Nobu was courteous and professional. First experience here ...and all good! read more

Our 2016 ATS-V needed an oil change and we always have had Nobu as our Service Rep. He is always very good but on this service, he was exceptional. He went went above and beyond in getting something that was not under warranty repaired at no charge. The honesty and extra effort is not typical for service departments but Mark Christopher Cadillac and Nobu are excellent and highly recommended. Thank you... read more

Please don't buy a vehicle here. They are the most dishonest dealership I have ever dealt with. The deal I made changed when it went into finance. I can't get anyone to call me back. I have consulted with legal counsel and I will see where that goes. Really saddens me to see this. read more

My husband and I had a great buying experience with Cesar Valenzuela. He made us feel comfortable and he was not "pushy" in the sales. He listened to what we wanted, really listened. Cesar made us feel like we were friends just hanging out- no pressure! He was patient with all of our questions and concerns. He was very informative about all of our options and discounts/rebates available. This was our first brand new vehicle purchase- he made it an enjoyable process (which anyone who has bought a vehicle before knows that is not an easy thing to do!). We would definitely recommend Mark Christopher Chevrolet and ask for Cesar! read more
