Testimonials

I would recommend them. I have an old idi non turbo and all I did was call and describe the issues I was having with my truck and the guy was very knowledgeable and told me the likely issue with the details and descriptions I gave him and he was spot on!
Kevin Tucker

These guys were able to diagnose it quickly and were straight up about the repairs required. They didn’t try to sell me on anything special, they took care of the repairs that were needed in a most cost effective manner and offered suggestions on repairs for the future…
