RT Clapps was able to get my vehicle fixed with multiple issues in a timely manner. Thanks to David, I appreciate the extra effort you put in to get my vehicle running better than it was. Thank you very much. I finally found a good repair shop I can depend on.

This is my fourth time using RT Clap Automotive. They are truly exceptional! This time I dealt with David and he was fantastic. Incredibly informative went out of their way to meet my tight schedule and demands and their pricing is exceptional. I don’t think there’s a better repair shop. I own six vehicles and I’ve never had experiences like this consistently, thank you guys so much! Emmanuel

This place is top notch. I had my car breakdown on me out west by turkey creek at 8pm. It started sputtering and was a struggling to drive. I stopped at the closet repair shop and left it with them to diagnose. The got back with me saying it was going to cost me about $3300 to fixed the issue. So I continued to call around and ask other places. I found RT and I explained the situation. The suggested several options and referred me to another shop to see what they could do for me as well as offered what they could. The quick cheap option the refered wasn't possible so I took the car to RT, they checked it out, offered me a more affordable option to fix the car than their original option and scheduled my appointment. I got the work done first thing in the morning, service was impeccable and workers were pleasant and very helpful. After they fixed my car, the was still a little hiccup in my exhaust system. The immediately pulled my car in, diagnose what the issue was and fix that problem on the house. I cannot recommend these guys enough. If you are ever in need of someone to work on your car make this one of the first calls you place.

My old Toyota pickup would not start. Clapp tried everything. They finally found it was a rare part, and everything works fine now. I know any other repair place would have given up on this little jitney and told me to scrap it. I thought of the great guys at RT Clapp this morning when I fired her up and cruised away.
Response from the owner:Hi Larry, thanks for the great review! We're glad we could pinpoint the issue and get you back on the road quickly. Always happy to help with friendly service!
