I have a "newer" car (2017), so it was a bit more, but I was happy to pay for the convenience and great service. There were only three people ahead of me, about a 30-minute wait, and I was in and out quickly. Sergio was amazing... very friendly and attentive. Easy pull-up spot and one of the few places open on a Sunday. Highly recommend.

Arriving I wasn't sure where to park and left the car near the building. Upon walking in, the attendant got my information and my key and told me to have a seat. I opened my computer to do some work. Before I could get much work done the car was ready, with results sent directly to the DMV. Nothing fancy, but Piedra's got the job done. I'll be back!

My car was due for a smog star test and he made it very simple and quick, understanding my car needs and questions. There are also seats to wait at and lots of places across the street to stroll. After 10 minutes, the exam was complete and results were sent to the DMV. He even suggested a place you could get the renewal on the same day! Otherwise you can pay online after 3 hours and receive your renewal sticker in the mail. I had another question about my car and Ahmad told me I could drive back and he can take a look. He was so friendly and knowledgeable, fixing the issue and double checking the car. Other clients I saw were all treated very kindly with smiles all around. Ahmad is truly a genuine and kind hearted person that cares about his customers and I would recommend coming over to him for your smog tests! STAR APPROVED!

And as a hobby mechanic, sometimes my work only makes sense to me. But Mo took the car in, listened to my explanations of some of its idiosyncrasies (won't hold an idle until warm, the rad fan is manually toggled... you know sh*tbox stuff) and performed the smog. What I felt at his shop was that I felt valued as a customer, not just a nuisance hobby mechanic looking for a professional to clean up their mess. He was kind, patient and got the car to pass. Will be coming back with my other sh*tbox Volkswagen.
