What Our Customers Say​

Attentive, knowledgeable, and attentive after sales service. Shaun and TJ quickly diagnosed the issue and repaired the work order same day. Reasonably priced! Next time I’ll remember to use their online coupons. Highly recommended…
Henry Liu
I went in for a smog check. The employees were friendly, and the whole process took about 30 minutes. I will definitely be returning the next time I need a smog test.
Justin M
I've been taking my car here for years, and they are always so nice, so helpful, and very honest. Definitely my top choice of mechanic, even when I moved two hours away. Highly recommend!
Kikii Werner
These guys got me right in and offered to bring my car to me because I worked so close and was worried I wouldn’t make it back before they closed. Superior service. Friendly staff.
