Maybe they should update their name to AA No Smog -- or at least start responding to Yelp messages and phone calls from customers.

I showed up on time. Only had one other person waiting at the time to complete theirs. Five minutes later, my vehicle was being taken in for the biannual test only smog check. He completed the test only small check in about 10 to 15 minutes, entered everything into the state computer and I was out of there within 30 minutes. The gentleman was excellent with his customer skills made you feel at home relaxed. Also, the facility is very very clean. You're able to sit in a clean environment with a restroom close by. Yes, I'm going back next year!

My advice go to any other local shop that would be of service rather than to take advantage of a sibling or elderly trying to pass smog.
