Our Reviews
I took my truck in for an oil change that raidien set up for me she made it very easy for me all I had to do was be there for my appointment and everything else was taken care of. We waited there in the customers lounge which had coffee and snacks with a tv so it was relaxing, time went by fast while they did the service on my truck! Definitely going back again for any service needs done on my truck!
I had such a great service experience here! Rayden scheduled me a same day appointment for a check engine light diagnostic and I love that she communicated with me beforehand that I may have had to leave my vehicle. Made my experience easy and I knew what to expect before arriving!

I had a great experience at Mark Christopher Auto Center. Nate Heath in the sales department was extremely helpful, knowledgeable, and professional throughout the entire process. What stood out most was that he was never pushy or made me feel pressured to make a decision. He took the time to answer my questions, explain my options, and made the whole experience comfortable and straightforward. I really appreciate the customer service and would definitely recommend Mark Christopher Auto Center, especially Nate, to anyone looking for a smooth and hassle-free car-buying experience. Have now purchased 3 vehicles here and will be doing so again in the future.
