I was told to just come in as it's a first come first serve service. They charge $50 for smog check only if the car passes. The address is correct as it took me to the right place, easy to find, and the person that helped me was straight forward. He asked for some information about the car, and then got on with the test. After the car passes, I paid the fee and was on my way. I'd come back here again for next time I need another Smog test.

Today was no different. I recently bought a used car and needed a smog check for the title transfer. Thankfully, Daren took the time to double-check and realized the vehicle had already been smogged when the previous owner renewed the registration in February. Since smog inspections are valid for 90 days, I was all set! If it weren't for his attention to detail, I would have spent money unnecessarily. Thank you to Daren and the entire team--you guys are the best!

Went to smog test my 1995 Jeep Wrangler at another smog place and it failed. They advised to go to…read morea smog certified repair shop, and looked on Yelp and found Crescent Auto. Called on a Friday at noon and spoke with Jeff and told him my Jeep didn't pass smog, and what the fees were to diagnose the problem. He let me know the fees and said we could bring it down today and he would probably have it over the weekend to see what was going on. Dropped it off right away, it's only a couple miles from my house, and Jeff called with an update on Monday and said what the problem was and how much it would be to fix it. I approved the charges and he also said they could do the smog test and certification too. Great! I don't have to take it to another place to see if it passes, Crescent Auto will do it all! Got the Jeep back, Jeff explained everything and gave us the detailed invoice with the smog certificate and off we went. My husband usually works on our vehicles, so this was a first for us to take the Jeep anywhere and it was definitely in good hands with Jeff and Crescent Auto. The communication was clear and we were updated often. I appreciate you Jeff and am so happy we found you and your shop!

This smog check business was very unprofessional and participates in false advertisement…read more They advertise online and on their own website to be $36.75 with a coupon digital or paper. I showed up and the maintenance professional hooked up my car without talking about pricing. After he completed the smog check he handed me the bill and I showed him the coupon. He would not honor the coupon and said I need to show it to him before he touches the car. I had to pay $61.75 plus $8.75 for the certification fee for a total of $70.50 False Advertising.

While inquiring with the technician, I have received a rude attitude by the way he interacted with me. I asked him if he's okay because he seemed irritated. Started arguing with me and I just asked him to stop so we could just proceed why I came for. Would t want to settle down and began taking pictures of me while finally declining service. I've been in this shop quite a few times and received excellent service from either of the two brother owners. Regretfully decided to leave for the kind of rude and weird behavior by the attending technician.
