Customer Reviews

  • A heat shield had fallen and was hanging underneath my car. I called Marks in the morning and brought it in after work. Within an hour they had reattached it back where it’s supposed to be, and had noticed my tires were low so filled those for me. Above all, I was thrilled when he told me there was no charge. I’m very happy!!

  • I had my car brought in because I needed to replace my brakes and Marks Auto was very flexible with my schedule to complete the repairs and they were very communicative with the process. I also appreciated the financing options that they offered and now I can drive my car again with peace of mind. Thank you Marks Auto!

  • The staff was very professional and at the same time just good ‘ol boys. Laugh and joke around but work gets done right the 1st time. They diagnosed my car within a day and sent me a list of procedures that were recommended and what needed to be done. Basically I got my car back within 48 hours. I highly recommend this shop!

  • First time at the shop and I was very impressed. Excellent customer service. Easy appointment setting. I received a really fair quote for some repair & maintenance work. I think I found my new regular mechanic shop. Highly recommend.

    — R.M. Odell

  • Very happy with the work AND the customer service! Dallas explained everything that was wrong with my daughter's car to me in a way that I could actually understand. Thank you very much to Dallas and the mechanics at Mark's for doing such a thorough job and for making her car safe and reliable to drive! Highly recommend!

    — Donna Butterfield

  • I brought in my Mazda due to a blown tire. The guys at the shop were extremely knowledgeable and professional and immediately diagnosed what had caused the problem and got to work fixing it. I'll absolutely be going back in the future. If I could give more stars, I would.
