If you are looking to purchase/lease a vehicle I recommend Mark Christopher Auto Center. Jose Enciso is the Internet Sales & Leasing Consultant who helped me with my purchase on Tuesday and he did an awesome job. He listened to my over the top requests and went above and beyond along with other staff to get the deal that I wanted done. I've been through the process of buying a handful of times and spending my whole day at the dealer was stressful and tiring. But this experience all happened through email, text and my cell phone and it was one of the easiest transactions ever! Plus if you can't make it out to the dealer to sign on the dotted line and pick up your new ride, no problem they will deliver it to you wherever you're at. My truck was delivered to me at work, sometimes we Simply don't have the time to go. I truly recommend Jose Enciso @ Mark Christopher Auto Center 2131 E Convention Center Way Ontario, Ca. 91764 (626)757-9583 for your next stress free auto purchase. read more

I wish your team cared when I was working this deal with them and left work early to get this done. The truck is gone now, so I'm not sure what help you would be to me. Maybe if you were there to correct their shortcomings, you could have helped. Your sales guy had the nerve to try and blame my bank for the failures your staff exhibited. "Not capable of sending a signed purchase order, I did receive a bunch of blank pages." They even suggested my banker just wanted to do the bare minimum when, in fact, that was your team's attitude. The funniest thing about this is, I came to your team to buy a truck. Your team did very little work on this deal other than asking management if my offer would be accepted. When it was accepted, your staff tried to make me feel like they had gone above and beyond. "This was a statement I got in a text from a phone ending with 9727." After Frank Vera confirmed to my friend with 2 different emails that you still had the truck, your team seems to try and make people feel like they are doing you a favor by selling you a vehicle. I emailed you this morning. If you would like to discuss something, that is where I do it. PS: I never asked your team to save the truck for me because they couldn't even get me the signed purchase order so I could get the check and head your way. read more

My husband and i have been shopping around for a Yukon xl at4. Just before 11:30 today, my husband called this dealer and spoke to Anthonny regarding one that we found online. My husband provided the stock number and asked if it was available. Anthonny advised that it was indeed available and asked when we could come down to look at it. My husband advised it would be about an hour to get out there (we live in north Orange County). Anthonny then proceeded to tell him that he'd pull it aside, have it washed and gassed up so that we can test drive and possibly take it home.. (email attached below for proof of appt time that was made) We got loaded up (2 kids and a newborn) and made the drive out to Ontario. Upon arrival, Anthonny came out, said hello, and said he would go grab the vehicle. A few minutes went by, and he came back and informed us that the car was not on the lot and that it was a demo car that was being used by the owner's wife. He then proceeded to tell us that he had pulled the car aside for us; but that he was not able to hold the key (implying that from the time we called to the time we got there, she had come and borrowed the car) He then tried to sell us on a AT4 Ultimate; which is another 20k and did not help the situation. He could clearly tell that we were frustrated, and went to "make a phone call". While he was gone, another gentleman Alazar came in and talked to us. In doing so, he clarified that the vehicle was never on the lot and the owners daughter was driving it. As a family owned dealer who strives for customer satisfaction, this was a very frustrating and avoidable experience had Anthonny actually taken the time to make sure the vehicle was there. We wasted almost three hours of our day and ended up with no vehicle.. will not be recommending this dealer to friends or family. read more

William in the Chevy service department is absolutely the best! I came in for a battery issue and he made everything so smooth and easy. Highly recommend! read more

They don't honor their own prepaid service agreements and tried to charge me $400 for an oil change that was supposed to be covered. I didn't think I'd have to deal with this type of behavior from Cadillac. Very shady and dishonest service department. read more

I brought my truck in for a simple transmission diagnostic on a Tuesday morning at 7am sharp. They did not start looking at my truck until 2pm the next day, and only after I called them several times. It seemed like they forgot about my truck because the dispatcher had to physically hand a tech the papers for my truck. I thought going to the dealership would be better than a transmission specialty shop, but not now. I will not be going back to Mark Christopher unless there is something very wrong with my truck. Also, Eddie likes to talk over you when you call with questions like, "is it normal for it to take this long?" read more

Went here after going to 2 other dealerships in my area , called the day before made my appt with Max and drove in this am to Anthony my service advisor and he got my car in the system and it went back about 8 am. Anthony said about 2 1/2 hours I waited for my car I did not drop off. Exactly at 9:40 car was completed. Not bad at all, 1 hr and 40 min. I was so pleased. Car is good and I was happy enjoyed the free coffee and relaxed a bit. Thank you Anthony for making my First experience excellent with your dealership. I'll see you in 6000 miles! read more

Thank You Mark Chris Chevy for having Rami on your sales staff!!!!!! He's the reason we bought the truck at your Store!!!!!! I will recommend Rami to other looking to buy GM products!!! read more

Jose Enciso was amazing! I worked with him all day today and told him I didn't want to be stuck waiting around to sign paperwork. He kept his word--called me when everything was ready, and I walked in and was out within 30 minutes with my new truck. Thank you guys! read more

Mark Christopher Auto Center - Jose Enciso was amazing! Definitely will come back - Car Dealers Near Me - Ontario, California

Good morning all, I honestly don't even know where to begin with the worst customer service experience I've received -- not only from Mark Christopher Chevrolet, but from a GMC dealership in general. It's beyond frustrating when you cannot get in touch with anyone willing to address concerns professionally or ethically regarding a business line of credit process. I repeatedly attempted to speak with a manager or supervisor, only to constantly hear that they were "in meetings." Each time, I left my full contact information, name, and phone number, yet no one ever returned my calls. On Monday, May 18, 2026, around 10:00 AM, I called the dealership and specifically requested to speak with the General Manager. Once again, I was told they were in a meeting. I left my information and waited until Wednesday -- still no response. On Wednesday, May 20, 2026, I called again and requested the General Manager. Shockingly, they were "in another meeting." At that point, I once again provided my contact information and here we are on Thursday, May 21, 2026, and I still have not received a single callback. It's disappointing that basic customer acknowledgment and communication seem impossible to receive. At this point, it feels like you have to be an actor, athlete, or Forbes-level business owner just to get the respect of a returned phone call. Customer service and accountability clearly need improvement. read more

Showed up to look at some Cadillacs. Met with Jose Enciso who was a great salesperson for us. He was able to answer all our questions, showed us multiple vehicles and we never felt rushed discussing the car info or financing. Jose was very professional to work with and was able to make a deal we couldn't pass up. Thank you! read more

My family just purchased a 2026 Yukon Elevation XL. Let me just say this was the smoothest, easiest transaction I have ever dealt with. If you need a vehicle, contact OZZY. Ozzy went above and beyond for my family and I. I met Ozzy a couple months back when we first went to look at Yukons, and right from the start Ozzy was professional and actually listened to what we wanted. He never pressured us or tried to just sell us anything. Last week, I hit up Ozzy, told him the exact Yukon my wife wanted and guess what? Ozzy MADE IT HAPPEN. I actually had my own credit union loan.... And his team even got me a lower interest rate than my own credit union. Overall, I'm completely satisfied with Ozzy and his teams customer service. Thank you for everything! read more

On my way to Tijuana I stopped Sunday at the gas station close to my house and at the time to start my GMC terrain it didn't start, called the tow truck company and had it deliver to the dealership, swapped cars and went along to celebrate Father's Day, called Monday, Tuesday and today Wednesday and still no call back and no answer on the diagnostic of the car, I didn't know that service on this dealership was bad!! read more

Mark Christopher Auto Center - Service Bulletin - Car Dealers Near Me - Ontario, California

I regret buying my vehicle from Mark Christopher Chevrolet. My car was sold to me with an exhaust leak, which should never have happened in the first place. I brought it back expecting the issue to be handled properly, but although they attempted a repair, the problem was still not resolved. What was most disappointing was the lack of concern for how their proposed solution would affect my family. I explained that being without my vehicle for several days was extremely difficult because I have an autistic son and reliable transportation is essential for our daily routine and responsibilities. That did not seem to matter, and there was no real effort made to find a workable solution or show understanding for my situation. The overall experience felt dismissive and uncaring, especially after purchasing the vehicle there and expecting basic accountability when a serious issue came up so soon after purchase. What made the contrast even clearer was that another Chevrolet dealership -- where I did not even buy the car -- immediately treated the situation with more urgency, compassion, and professionalism than I experienced here. I expected much better customer care, especially after making such a significant purchase, and unfortunately this experience left me regretting that decision. read more

For some reason the service is going down hill. Website to make appointments never works " oops something went wrong" Some of the customer service people that help you do not seem to happy at times. Things we're better a long time ago. read more

Edited at 6pm that night. The business owner will reply to this message but never call you back when you call him. Add this to the list. This review would be 0. Your customer service is just so bad. At the time of writing this review, I have been in your service waiting room for over 3.5 hours with no update - which I was promised. The issue I have is that it adds to many other issues I've had since purchasing a new 2025 Buick - which I am here to get repaired even though I bought a new vehicle, need I add more. Other issues: not giving me the promised price - I should have walked away, I know. 3 electronic issues within 2 months of buying the vehicle. Poor customer service: I left 2 messages for someone to call me back for service, no one called. Then when I finally got someone, who said they'd get the right person to call me. That person pretended their phone was down and texted instead. If your text works, your cell works. Then today I am told it's going to take all day to fix my car, before anyone even looks at it. And am I ready to stay here all day. That's even though I was here at 7am. GMC called me 3 times but didn't resolve anything, Anyway, wish I had bought another brand at this point. Sigh. read more

They know everything about everything GM EVs. They sell them all too. Ask for Alex Sarabia. Alex is on his game, wants you happy. They will take the time for you to get familiar with your purchase. New technology and it's amazing. Alex will patiently and tirelessly glide you through to the fun EV familiarization if you want. Pricing was good - smooth transaction. Buy out of stock on the lot or they will be glad to order what you want. We wanted to order a Sierra AT4 EV and learned sales jumped 776% nationwide and they could gladly order us one. With its popularity going to take a bit longer to get but worth it. Trained technicians familiar with all phases of maintenance on your GM EV. 4.5 stars and if we have good service Dept experience we'll bump it to 5. Thing is, ya don't need to service GM EV's so 4 and a half stars for now. read more

Was looking around town for the best deal and of course the excellent customer service from the dealership team. Went in Saturday afternoon and got helped by Thomas Bautista, he did great, very respectful, knowledgeable and was not pushy at all. Next morning we sent in our expectations via email & we were promised best deal and came out with best deal, no games or gimmicks. Smoothest transaction I've experienced. I appreciate the staff especially Thomas for being great at what he does. read more

Incompetent service department, service manager should not hold that position.. they messed up the alignment on my corvette and when I took it back they fixed it but told me I'm not welcome there anymore like it's my fault your mechanics can't do the job right the first time !!!

Well unfortunately my luck ran out here... I took my truck in for warped front brake rotors (probably a warranty issue) and was told that my brake pads wear too worn and it caused the rotors to warp. I checked them myself and they were only 16% worn! Never going back again! read more

I purchased a vehicle and an extended warranty from this dealership. I requested to cancel the warranty within one week. It has now been almost three months, and I have received no response or refund. I have contacted the dealership multiple times and even emailed the general manager, but no one has followed up. This level of unresponsiveness is unacceptable and shows a lack of accountability. I strongly question the professionalism of this business. read more

If you're visiting this dealership, I highly recommend asking for Ozzy. I called on a Friday evening to check on the availability of a vehicle I was interested in leasing, and within just a couple of hours, I was driving off the lot. Ozzy was knowledgeable, informative, and most importantly never pushy. He let the car speak for itself, which made the entire experience feel easy and low-pressure. A tactic that many others in the industry could utilize! If you're planning to purchase or lease a vehicle from Mark Christopher in Ontario, ask for Ozzy. read more

Ask for Brady from Chevrolet. He's an awesome sales guy and is true to his word. Helped me out any way he could to try and get me into a Silverado. Although we didn't end up making a deal, his kindness and willingness to help me out goes to show what a great person this man is. Thanks Brady! read more

Shout to Rami for all his hard work and help! We picked our gorgeous vehicle that was a bit over our budget but he was able to make it happen for my husband and I. Very attentive, good listener, and overall great attitude. He was also very helpful with any questions we had and was so nice in explaining everything about the car. Overall- he is exceptional! Thank you Rami! We look forward to working you in the future. Also thank you Jerry for working behind the scenes to work with us and the financing process! You guys were awesome and we are very happy with our purchase! Looking forward to working with you guys again. read more

This is the third vehicle I've purchased from Mark Christopher. Always a good experience. Rami was an attentive and knowledgeable salesman.

Terrible service. Even when you have an appointment you still end up waiting over 3 hours for a 30-45 minute oil change. It took 20 minutes before even being acknowledged to get checked in. I would not recommend service here. Better service at Jiffy Lube. read more

The sales and finance staff at Mark Christopher Chevrolet in Ontario are awesome. Ramirez was knowledgeable and super helpful with helping me get my vegicle and appraised. He then went through the inventory to help me view different options on Chevrolet silverado RST that fit my needs. I was able to test drive it. He also brought back the sales numbers to help me finance the vehicle. He did a phenomenal job as did Cesar Valenzuela, the finance officer. I truly appreciate both of them working on helping me get over 10k in rebates to make my new vehicle super affordable. I highly recommend this dealership to anyone who wants to find a great deal on a Chevrolet vehicle. read more

Spent weeks trying to find the truck I wanted and decided to make the long drive to Ontario to go get it. Rami was super upfront with no BS. He kept it to me straight and that's all I ask for when I go looking for a new vehicle! We worked out a deal and everything went smoothly! Ask for Rami when you go! Definitely would work with him again in the future! Thank you Rami! read more

To think being a loyal customer of Mark Christopher Auto Center would mean something. I bought my Ford F150 here and even referred my brother, who purchased a brand new GMC Sierra 2500 Denali and today I brought my cousin to buy a new Chevy Silverado 1500. You'd think after spending real money here and bringing more business their way, they'd show some respect. What makes this even more disappointing is that I actually know Jerry personally through his older brother Ozzy. Originally I only wanted to deal with him, but he was off today. Either way I gave Jerry and his manager Ray a shot. That was a mistake. Jerry, who goes by Junior, acted like he didn't even want to help. His attitude was off from the start, no energy, no urgency, no effort. Ray started off cool but switched up quick. It felt like they were just playing games instead of trying to earn the business. I know their desk manager Mike , I know he has the power to make this deal happen. Instead of stepping in and making something work, he let us WALK. That's not what you expect after doing business and sending your family their way. Thankfully Rotolo Chevrolet stepped up. I told them I wanted to be at $650 a month with zero down, and they made it happen on a Silverado RST. Mark Christopher couldn't even beat that on a CHEAPER Custom Silverado. That's embarrassing for a store that likes to act they're all about volume. I brought my family here expecting to be treated like a valued customer and instead got treated like nothing. read more

This review is not on the dealership. This review is on GMC the Brand and GM in general. August 2022 I purchased a new GMC Terrain from this dealership. I've driven it 60,330 miles and the engine failed. That's unacceptable for a new purchase. They won't stand by their product and help with replacing the engine because it's just outside power train warranty. Buyer Beware. GM products aren't made to last. They have officially lost me as a customer after loyally buying 5 GM vehicles over the last 10 years. Don't waste your hard earned money time and money on junk products. read more

The best part of our buying experience was our sales agent, Gilbert. We went in to see 2025 GMC Sierra Denali, and ultimately knew that we were going to buy it. Now to the hard part - the finance part. My best recommendation is to take advantage of their tool online that enables you to apply for a car loan right then and there. My husband got approved right away with the interest rate in the 5's. Which is very fair for where they are at right now. Overall, I would definitely recommend to buy here and to ask for Gilbert! Even weeks later when I have questions or concerns- he responds immediately and answers my questions. Thanks Gil! We will be back for our Yukon XL :) read more

Avoid this place at all costs...we purchased a car here. The salesman upsold us on a warranty and told us it covered everything but tires and brakes. 4 months in we had a problem with a belt and service said it wasn't covered. I called the salesman's and he once again he said it covers everything but tires and brakes. When I asked about the belt, he said o yeah there is other wear and tear that's not covered. He said I should have looked over the warranty with finance before signing it. Spoke to the manger as well and he was zero help. These are the type of people that give car salesman a bad name. read more

I have to say I am really disappointed in Mark Christopher Auto Center. I have bought a lot of vehicles from this business in the past 25 years. However recently when I tried to schedule to bring in my 2003 HD K2500 Duramax, they refused to service it because it's over 10 years old. Which most of my GM vehicles are less than 10 years old. My past experiences with both the Cadillac and Chevrolet service centers had been outstanding. There's plenty of other options around to buy and service GM vehicles. I'll contact my sales people and let them know never call me again to buy a new vehicle or trade in the ones I have. I'll take my business to a place that appreciates their clients. Rotolo gladly is servicing it. They'll get my business from now on. read more

I had an appointment to get my truck serviced at 9 45 today. Eddy tells me its going to be about 2 hrs wait and I said its fine. I see my truck seating for like 1 1/2 hours so i go to eddy and I said are they going to start working on my vehicle soon and he said my vehicle is next. I wait another 45 minutes and my truck is still sitting in the same spot I get that they are busy but why do they tell me my truck is going to be done in 2 hrs and that is not the case. This is my first time at service for my truck and since I do not have to pay they are leaving my vehicle for later. Horrible customer service. I left without any service being done to my truck. Eddy told me I can call him to reschedule but I told him this is the first and last time I am coming here for service. And in the future I will not be buying anymore cars from mark christopher read more
