What Our Customers Say

I came here without a clue of what happened to my car. But when I walked in and met Josh I knew he’d make sure it was taken care of and that’s exactly what he did! He was great at communicating with me every step of the way and explaining it all in a way I understand but didn’t feel stupid. Most mechanics shops see a woman and think they can get one over on you. Josh wasn’t like this, he was kind and compassionate. I’ll never go anywhere else and I’ll only deal with Josh! I recommend asking for him when you go! Thanks RT Clapp!

John D.

Good experience! They got my 4Runner right in, I was out with in an hour! Very fair price and friendly fellows to work with, I’ll use them again!!

LeaAnn P.

Explained everything and walked me threw it with ease. I had to work while they fixed my cars and they called and kept me in touch with processes and if they found any problems I would recommend them to anyone and everyone!! Awesome job 👏 👍
