"I'd highly recommended them. They're very good at doing work with ignition problems and they're very knowledgeable. I like the fact that they were able to diagnose the problem fairly quickly and come up with a solution. They're a specialty shop and they have diagnostic equipment that most of the other places didn't have. They fixed an ignition problem that I had and I had them do the smog certification. They're very knowledgeable." -Scott H.

"I thought they were very fair. I asked the owner if he could explain things to my son, and he took the time to explain everything and showed him what needed to be repaired. Since my son was paying for the repairs, he had a better understanding of everything that was involved. It was a very fair service, and it was done in a timely manner. The price was what he said it would be. " -Linda E.
