He explained the process clearly, answered all our questions and helped us feel confident every step of the way. The service was efficient and thorough and we were in and out in 15-20 minutes tops! What impressed me most was how smoothly everything went the next day. I was able to renew our tags online, and the DMV had already been notified by Mission Smog Check. It's clear they take care of their customers from start to finish.

Cheaper than most, considering I wasn't trying to drive 17min for 38$ I paid 58$ for the convenience since it was in my way home and I had other errands to run. Update: the other errands to run were an oil change but connected to this place next door they do oil changes. Synthetic blend was their cheapest they don't do regular, but it was the same price as Lenny dykstras and saved me the trip. Although it didn't come with a free car wash like Lenny's, still very convenient.

While inquiring with the technician, I have received a rude attitude by the way he interacted with me. I asked him if he's okay because he seemed irritated.

I've been in this shop quite a few times and received excellent service from either of the two brother owners.
