“I had a coupon for this place since the smog check place I usually go to was trying to rip me off so I thought I'd go here. Asked if I could use the coupon. The guy said yes. Was in and out in 20 minutes or less. Guy working was about his business and gave me all the paperwork I needed. Good place fast service.”

“This place is great. I walked in today with no appointment. Super fast, no wait time, very clean, and really nice guys. It can be a little intimidating as a female to walk into any auto shop, but the guys working here are honest and gentlemanly and, as I said, really nice. Check them out!”

“Went here on a Sunday about an hour before closing.  In and out in less than 15 minutes.  Very pleasant experience.  Got a coupon for $30 off online which helped with the pricing.  This was my first smog check in CA so I am not sure what prices should be and was more concerned with finding a place to get this done on a Sunday. Easy transaction.”
