When we…read moregot there, the smog agent quoted us $91, plus the cost of the certificate (at around $8.25). That's $100 for a smog check on a 2015 bmw. I had to explain to the smog agent that I've had business with their smog station before via yelp and I had no problems with the agreed upon price, but the agent kept getting confused and tried to swindle us as customers. I had to show him the yelp conversation three times about who I spoke with and the agreed upon price. Under no circumstances go here. Instead, go down the Northbay smog on la goma? They charge $76 flat for everything and they won't give you a hassle like these people.

You do have to down load a coupon but I'll attach it to my review so you can just show them and get the discounted rate! I called the facility around 4pm and asked if they could run a smog check on my Toyota Prius that day and they said yes! I arrive at around 4:40 and they saw me immediately with no wait. They ran a few tests which took about 15 mins. The total price was $40+$8 card fee so just under $50 which is a decent deal. I've been to other locations San Francisco as well and this is pretty much the lowest price you can find. The guy running the test was polite and efficient. He did make me wait out in the cold though when I could have just sat in my car and not affected his testing but whatever. Also didn't wear a mask the entire time which seems to be consistent with other people's reviews about not being "COVID safe." Overall, I had a pretty easy in and out experience which was reasonably priced.
