The service reps are always caring and professional. They explain everything to me. This particular service trip, my fluids were not topped off. Maybe an oversight on the part of the service tech.

Once it was finally fixed, I had to take it back the following week for a noise it was making. They had it all day and did not figure out what was wrong with it. I ended up taking it to M.K. Smith. Not only was it fixed but it only took the morning and it was done. More

He helped me draw up some financial numbers and we were able to make a great deal on a new vegicle. I appreciate the stress free process and time to look at dealer inventory. I highly recommend Mark Christopher if you're looking to buy. I'd come back again to do business with them. 10/10 on the customer service! More
