I got a smog check here the other day. Overall, it was a pretty smooth process and the Stanford coupon ($30 off smog check) makes it only $37, which I understand is a very good price. You need an appointment for the smog check, but when I called them the day before my appointment at the DMV to register my car, they were able to get me one after 5 pm on the same day. The guys helping me were really nice, the smog check went fine (my car passed) and the price was right, so overall it was a good experience. My two complaints are: 1. It took an awfully long time. I'm not sure how long these things normally take but I was there about 45 minutes which seems long to me. They also don't have a great waiting area. There's a bench but it's in the sun (although one of the guys dragged over an umbrella for me to make it shaded) and then there's a tiny convenience store but that doesn't have any seating and I don't think you're really encouraged to hang out there. I did though, because it was really hot that day. 2. They fiddled with the steering wheel position. When I got in my car it seemed like they had really tilted the steering wheel back and it was so uncomfortable for me to drive it that way but I couldn't figure out to adjust it. When I got back to work I called them and asked them what they had done with it and they swore they didn't touch it and they just adjusted the seat. I started to think I was going crazy. Today I looked online and figured out how to rotate the steering wheel (its the lever that's...on the steering wheel, duh) and got it back much closer to where it was before, so its all good. But they definitely moved it! I'm not sure why.
