Fantastic experience with Tri-Valley Automotive - I’ll even go as far to say this is prob the best auto shop I’ve found yet. Took my car in for a few warning lights that came up on my dash, and found out the vehicle needed aprox $2,700 worth of labor & repairs: re-sealing upper and lower timing belt covers/ resealing oil pan/ wire work / broken coolent component + extra services. I have a pretty good understanding of how an engine works, but with that basic knowledge I end up asking a lot of questions when work is performed - not only because I’m curious, but b/c I want to fully understand the scope of the repairs. Owner Don, and the tech working on my vehicle, took the time to answer all my questions and on multiple occasions visually showed me the work progress while it was on the lift. I feel very confident that everything was repaired to spec, and buttoned up professionally. The charges were reasonable, and I was updated continuously on any increases. Bonus: they use a text feature to alert when the vehicle is being worked on & completed. There’s also a customer referral program, and a oil change loyalty program. Go to Tri-Valley Automotive! :)
