    Quote I received from Star Smog: $54.75 smog fee + $8.25 state certificate fee, totaling $63.00.

    I called Star Smog and they gave me a quote of $63 for my vehicle. Got there and they told me my Promaster van is an RV, it's not ... it's simply a van conversion, and that it would be $180. They told me what turned out to be a complete lie that the RV classification is mandated by the state of California. I obviously said I wasn't going to pay $180. The woman said, let me check with my manger, came back and told me they'd do it for "only" $100. On top of the run around I got and the lies, the woman gave me somebody else's paperwork when I told her I was going somewhere else. That other customer was in a panic, understandably. I did the right thing and returned the other person's paperwork to Star Smog and got my own, which I no longer actually needed. I went literally around the corner to a place on North Main Street, no waiting, smog check completed in 5 minutes for $65 flat fee - out the door. No jacking around, no made up/fake RV fees, no lies, great customer service. I'm disappointed to post this as my wife and I have been going to Star Smog for many years without incident but I highly recommend you avoid them now. UPDATE Star Smog posted a response to my review so this addition addresses their response. This WAS the Walnut Creek location. I both called and got quote via email from Star Smog located on 1225 Parkside Dr., Walnut Creek. I have ATTACHED the estimate i received for $63. I stand by my review. It's time for this business to review their operating procedures and business practices. Charge what you like, even if it's not competitive, but never lie to customers. Be straight forward and honest with them so customers can make informed decisions.

    Bay Side Smog Service is always outstanding!…read more I've been here a few times with different cars, and they are consistently friendly, accommodating, and quick. I've always been able to get an appointment the same day or the next day. They're located toward the end of the parking lot once you pull in. The smog check itself usually takes about 15-20 minutes, and there's a small office where you can wait while they complete the inspection. Once you pass, they provide the paperwork right away, and I've been able to renew my DMV registration within a few hours. If you need a smog check in the area, I definitely recommend checking them out. Great service, convenient appointments, and a very quick turnaround!

    FINALLY!! A smog place I (and you) can trust…read more I came here as a last ditch effort in attempting to smog my wifes 2015 Chevy Malibu. We were getting some bad codes that prevented it from being smogged and I went to another smog place in Concord. I was sold approx $800 in repairs and THEN told that I should call CarFax get a quote and take it and get rid of the car! This 2015 Malibu is hardley drive as I work from home 100K milles. After hitting another auto repair place it was told to me... Im betting this would pass go to BAYSIDE SMOG... I did and Im glad I did. Retold my story to Naqib and he smiled and stayed neutral on it while seeing the disbelief in his eyes on my being told the car would cost more to repair and smog than to just "sell it as is" It took them 15 minutes maybe to smog the car with no issues... no weird side gimmicks or tricks, the car just passed as it was. Bayside has a lifelong customer and Ill steer everyone needing a smog to this guy. Solid service!
