Our Reviews
Juan Fletes is the absolute best service representative I’ve ever dealt with in the automotive industry!! He always provides remarkable service and I’m truly grateful he is a part of the Mark Christopher team. Give that man a raise!! ;-) thanks ~ Craig Mauk
I bought my new truck there and it was a very pleasant experience. Jason and Emerterio were easy to work with and I got everything I wanted at the price promised. I will go back there for my next purchase and I recommend this dealership 100%.
Alazar was a true professional. Welcomed us in with open arms! Made us feel welcomed right away and was very attentive to detail. Great listener and leveled with us in a great manner as we juggled different trucks and prices. Alazar really helped me find a brand new beautiful GMC Canyon that I can comfortably move forward in financially. Not only did he help me find an awesome affordable truck, he got me into a brand new truck that wasn’t expected! Mark Christopher has a team of true professionals and Alazar was a great representation of that! He made the whole process fun and smooth!
Jason was very helpful. We called about finding a specific car, and he had it all ready when we got to the dealership.
I always take my car to the dealer for the service and I like that they send coupons that can be use.
Jose notified me once the 2025 Ultimate Yukon Denali came in. The staff worked with us to get the monthly payment close to what we can afford. I’m very happy with the vehicle.
THE SALES PERSON MIKE SHERIDAN HE WAS PROFESSIONAL AND COURTEOUS AND VERY KNOWLEDGEABLE IN THE TRUCK I WAS INTERESTED IN I REALLY APPRECIATE THE SERVICE AND HE HELP ME WITH THE PURCHASE OF THE TRUCK 4 STAR TO HIM
I am a repeat customer with Mark Christopher now for 2nd time. this time i was in the market for a pre-owned Silverado and this was my go to location. Jose Enciso was the sales rep that helped me review and locate through all their used trucks inventory to find what i needed best. I am very happy with my purchase and how easy the sales process was, there was just some slight hiccup with the warranty on truck but we were able to get it resolved and Jose did his best to take care of our deal.
If you guys are looking for your next vehicle, look no further! Ask for Armando Nuno, he's experienced and knowledgeable in your car buying needs! He helped me get into my 2025 Silverado turbo max. He made my car buying experience memorable! It was fast and easy and I recommend my friends and family to visit this dealer!
I recently purchased a new Chevy Malibu from Johnny Mendoza at Mark Christopher Auto Center. My experience was the best I have ever had when purchasing a car. Johnny and Joe G. went above and beyond to make the entire experience as quick and enjoyable as possible. They were both friendly and knowledgeable and listened to my needs. In the end, I left with the car I wanted at the price I was comfortable with. I would definitely purchase my next vehicle from Johnny at Mark Christopher.
My husband and I were looking for a new family car to fit our needs. We were interested in the gmc acadia elevation. Joel answered all of our questions and worked with us until we came to a sale. Even following up with us a week later to make sure we are just as happy with the new purchase. I know we will be taken care of at GMC.
Came in on a Sunday evening to just ask questions about trading in my truck for an suv, thanks to Rami Mahroom he kept it simple and didn't bs me, within two hours left with a 2025 and my 2022 stayed. Thank you guys
Julie went above and beyond to get the repairs done in a timely manner. Great communication on her behalf. Didn't have to stress about the repairs actually being repaired unlike rotolo chevrolet.
They ordered my part and notified me when it came in. They were waiting for me when I dropped off the car. They had the car ready when I arrived. They were very professional.
Jerry Peńa keeps assisting me even after the sale and also jeeps following up to see of i need anything.
Tony provided excellent customer service & was clear and concise on all of his responses. I appreciate the overall experience.

(Translated by Google) It was an excellent transaction in the sale, thank you Jr. Good job, I recommend it. (Original) Fue una excelente transaccion en la venta gracias jr bue trabajo lo recomiendo
The work done was the replacement of the transmission harness. I already knew that the catalytic convertor needed to be fixed and the I thought the strong smell was exhaust fumes. Nobu even smelled it when I checked the car in. I got my vehicle back and I went to an independent shop 2 days later to have the catalytic checked. It was raised up on a lift and they clearly saw a fuel leak around the gas tank and showed it to me. I called Nobu to find out why the mechanic didn't inform him of this since it is a safety issue. I don't blame Nobu with this since he doesn't necessarily go under the vehicle. I am disappointed that the mechanic didn't say anything about it because the leak was pretty obvious. Regards, Ariel
Very helpful and were able to make the deal happen. Good variety of trucks to pick from
Jason did a great job explaining the details of the vehicle, the process, and the overall experience. I would recommend mark Christopher to anyone, will definitely be back for future vehicles. I look forward to servicing my new truck with the dealership.
Greg and JC were absolutely amazing towards helping me purchase my new truck! I absolutely love my new vehicle! I initially went to a different dealer ship prior to Mark Christopher, it was not a pleasant experience! JC made a deal with my trade in which I felt was reasonable. I ended up getting an even better truck and deal than the previous dealership! The process wasn’t a headache, was fair in time and was a more humble and comfortable experience ( didn’t feel pressured or uncomfortable!). So happy with my experience! 👏🏻🎉😎… THANK YOU JC FOR EVERYTHING!!
Friendly service! Leslie was very helpful. I’ve been going for over four years. I take both of my cars.
