Our Reviews
Didn’t receive the best service from My first rep Mario Sanchez. I ended up working with Greg Hernandez who took over and provided great customer service.
We had a great experience, especially on a limited time crunch. The staff was very accommodating.
Very professional and helpful stuff at the Mark Christopher Auto Center. Rami my sales person was very helpful.
Jose was amazing to work with! He has an extremely positive and energetic personality. He made the buying experience fun and was super helpful throughout the process. He helped me set up all the bells and whistles. Buy your next car from him.
Overall great experience. Worked with Cynthia C. and she was so very helpful and kind throughout the entire experience. Answered all the questions we had and was very responsive. Ray was very helpful and great to work with as well. Overall amazing experience.
Juan has always been great but I was told my car had multiple issues which some were correct but I was told my negative battery cable was bad a ball joint and some bushings. I am a heavy equipment mechanic but don’t have the time or the want to work on my own vehicles but due to the price and work I decided to handle it myself and I am glad I did because after replacing my battery cable the old cable tested good and out of everything else quoted only my battery and wheel bearing were bad. I am willing to pay dealer pricing but not if I am not getting dealer quality work or service. I understand technicians are getting hard to come buy but there is no excuse for screwing customers.

A truley great car buying experiance. JC was very informative and supportive along the way. NOthing but great things to say about Mark Christopher.
Made an appointment with Taylor, one of their salesman. Showed up with my mom and told the receptionist there i have an appointment with Taylor. She paged him and told us to sit at one of the tables which we did. We waited and waited. Apparently Taylor was at the other building nextdoor and was in a meeting at the time. We waited for almost a half an hour. That wasn't the issue though. The receptionist and my mom got into a bit of an altercation due to the long wait. The receptionist called out my mom as being "rude" which she wasn't. There was a guy at the desk and she was talking to him. While hearing her, he was also staring down at my mom which made her feel very uncomfortable. Taylor eventually showed up and apologized for the long wait. A deal did eventually get worked out on a car they had that i qualified for, a 2027 Chevy bolt EV. 5 stars would have given if it wasn't for that altercation with the receptionist. If upper management reads this Google review. I did not get the names of the receptionist and that guy. We believe he's one of the sales manager there cause we saw him through out our entire visit, walking around the lobby area and also talking to others there. Our visit was on Friday, September 18th around 4pm. Aside from all of that, Taylor was and is a good salesman. Worked out the numbers and we got a deal done. That's really all that matters! Thankyou Mark Christopher Chevrolet for getting me into a brand new car!
