Tim and Mike made my car buying experience super easy. I never once felt pressured to buy something I didn’t want. Mike took his time explaining all the different warranty options and made sure I understood everything before I signed! Tim was very kind and caring he made sure that I got a vehicle that fit my needs as well as making sure that I had enough space for my twin boys and all their sports equipment. Thank you so much Tim and Mike.

Thank you for sharing your experience. We’re glad Craig and Michael provided a no-pressure process and helped you drive away in the used Volkswagen Beetle you wanted. Enjoy every mile behind the wheel!

Had a very pleasant experience purchasing my new 2026 Acadia Denali. Sales consultant Fred Butler was more than accommodating, knowledgeable, and helpful in our process.

Everything with Suntrup has been first rate.The only negative is trying to schedule service online. I thought I had made an appointment, but I guess I didn't, BUT they were able to still fit me in.
