Customer reviews

Don’t take our word for it, see what our customers are saying!


My daughter is a student at UT. She had A/C issues. RT Clapp Car repair diagnosed and fixed the problem. They worked with her schedule to get the car fixed. Very reasonable priced too.

Darren W.

If you are looking for a trustworthy auto shop, look no further. RT Clapp has quickly become my go-to mechanic. They are quick to determine the issue, and they fix it for a fair price. They always make sure that you know the cost before making any repairs. HIGHLY recommend!!!

Shannon T.

We know in East Tennessee, it’s all about relationships and good service and for me RT Clapp is top notch. I couldn’t ask for anything better than what they offered when I got my truck serviced. Thank you.

Alan W.

They totally could have ripped me off but didnt and were super fast and transparent. I will be coming back.

Tom B.

Excellent service, fair price. I was traveling across the country and broke down in Knoxville. A call to this shop with an explanation and they had my car in and a repair done in less than 48 hours. I was back on the road. I cannot say they are good at everything but I can say they did right by me and my family. I highly recommend.
