Our Reviews
Exelent services
The Mark Christopher team treated me respectfully and professionally. They made it easy for me to get into my dream truck at a fair price with no hassles. This is my second truck I purchased from them.
Process and transaction was good, ran into a few minor discrepancies and hiccups with my trade-in but they were able to work it out and get me a good deal on my car and I left satisfied.
Great amazing fast and professional all the time would not change dealers for the world
Took my vehicle in for service and was greeted by my service advisor Jackie. Jackie was great with communicating to me what my vehicle needed and made sure my vehicle was done in a timely manner. I will only take my vehicles to her in the future.
They treat you like family here and Edy is the best It’s quick and simple
We had an absolutely amazing experience purchasing our 2025 Chevy Silverado from Mark Christopher Auto Center. From start to finish, the entire team was efficient, knowledgeable, and incredibly helpful. They made the process quick and easy, and went above and beyond to get us the exact truck we wanted. Both the sales and finance teams were fantastic to work with—friendly, professional, and truly customer-focused. We couldn’t be happier with our purchase and the service we received. We’ll definitely be returning to Mark Christopher Auto Center for all our future vehicle needs. Thank you so much for everything!
Great and friendly service. Would highly recommend.

JT was very helpful he made the buying experience easy. He was easily a 10 out of 10.
Eddie was very respectful and professional. But you need more help at service center. I took 31/2 days to get diagnosed on vehicle about problem🤷♂️
They did a good job. I have had this work done there before.
Great location awesome staff and very helpful. Got exactly what I was looking for. Much appreciated
Very happy with the service I was provided. Called on Thursday afternoon to inquire about a vehicle I saw online. Quickly I was connected with a sales associate who didn't give me the run around. We went straight to the point- no bs needed. By 6pm he delivered my vehicle to my house with no issues. Will definitely continue using them for all new purchases.
