Our Reviews
Jackie is wonderful! When my car broke down this dealer was closed due to inventory that weekend. I was told I could take it to another dealer but I chose to wait till I can take it to the one that I have used for over 10 years. Thank you Jackie and Team!
It was great, quick, and an easy transaction. I would recommend for people to shop for cars here! Very helpful and efficient.
My husband and I have never had a most pleasant, fast and convenient experience like the one from yesterday. Alazar and the financial agent were amazing! We really enjoyed every minute there, which was very fast by the way. We really appreciate all their help.
Very cool and helpful customer service! They take the hard side of negotiations and let you down easy! They even give extra test drives to make sure you are happy.
Jeff and Nobu were very helpful, friendly and great service. I highly recommend this service department. Thank you for always helping me with my service.
Jackie was great. Listen to all the issues and had them written down for the techs. Then after, reviwed everything that was found and how they were fixed.

Here’s a review you could use: I recently purchased a Hummer EV from Mark Christopher GMC, and I couldn’t be happier with the experience. From the start, Deangelo was fantastic to work with, guiding me through the process with professionalism and a friendly attitude. The entire team made buying this vehicle an enjoyable experience. They were attentive, knowledgeable, and made everything seamless. I would highly recommend Mark Christopher GMC to anyone in the market for a new vehicle—thank you all for making it such a pleasure!

Mario was very helpful for me. He was very polite, informative on vehicle, and he was always making sure I was fine or needed anything. He made my car buying very peaceful. We had a lot of similarities in our life and he is a good listener and a people person that I related to. I had a very good experience and the dealership too. Every body was very nice. I would recommend mark christopher dealership to anybody that will listen to my experience.

Great experience. I highly recommend this dealer. Mario did an outstanding job helping my wife and I purchase a car for our son. We drove an hour to get to the dealer. A trip well worth it to buy the car and meet an exceptional professional salesperson in Mario.
