They went out of their way to accommodate my needs. They explained every thing to me, and even took my motorhome to finish the smog testing.

Tim is the Most Amazing Mechanic I’ve seen in my 40 Years in the Car Business ! With 3 ways to fix the blend door ! He choose the one for the customer’s best pricing ! The dealer low balled Me & He took a 8 hour job to four hours . The factory set the HVAC actuators to the wrong pressure !

After 40 years in the car/truck business He is the go to Guy of Auto Repair . ??????

Founded in 1977 by owner Bob Weitz within the city of Napa. At the end of 2011 we moved to our new facility off North Kelly Road in Napa. Our new 15000 square foot shop located right off highways 12 and 29. Just a few miles west of the Coredlia truck scales. We pride ourselves with being one of the cleanest facilities in our industry today. We offer mobile road service for commercial vehicles in Napa and surrounding counties.

The guys here are always straight forward. Good prices and I don't feel like I'm paying for services that I don't need. I've been taking my personal car here for awhile and the company I work for gets their services done here. John S. Antioch, CA

I took my car here for what turned out to be a simple, small electrical issue. Instead, Carlos told me I needed a fuel injection flush - one of those things they upsell you too when you go to an oil change place. Only this one cost over $300! Carlos assured me that the problem was resolved. I ended up stranded at the side of a freeway two miles away. I had to get the car towed at a cost of over $150! The solution was easy, took 10 minutes, and cost me nothing at the place I towed it to. When I called Carlos to tell him I was stranded at the side of the freeway because of his poor workmanship, his attitude was dismissive, condescending, and unhelpful. He proceeded to tell me that he doesn't guarantee that his workmanship will fix the problem. Really? Imagine if your doctor treated you that way. Basically, he took my money and did nothing. I get the feeling that this place once was a good shop, but someone got greedy and dishonest. To be certain, Carlos is a good talker. He seems sincere and knowledgeable. But the emphasis here is on SEEMS.
