Quick and honest little smog shop, it's past the car washing area in the back. I was a little…read moreconfused at first. But they were fast and decently priced. Cheaper than most, considering I wasn't trying to drive 17min for 38$ I paid 58$ for the convenience since it was in my way home and I had other errands to run. Update: the other errands to run were an oil change but connected to this place next door they do oil changes. Synthetic blend was their cheapest they don't do regular, but it was the same price as Lenny dykstras and saved me the trip. Although it didn't come with a free car wash like Lenny's, still very convenient.

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.

After getting baited (low price advertised, then increasing it) by another smog check station, I…read moreproceeded to find another business that was more transparent. The prior business listed the smog check for ~$47, but it became $89 for a "luxury car." I even called to confirm the price. The person on the phone did not tell me, if you have a luxury car, it's going to cost more. If the business does not practice fair they do not deserve my business. US Smog Check on the other hand was very transparent in pricing and their workspace was clean. They have 3 workstations for the cars to get smogged; the drive in and out of the place was easy since the garage is a through and through. There was no additional cost for a "luxury" car because a car is a car. Different size cars with big engines (big trucks), different fuel (diesel), and year (older than 2000), I get the additional cost. They posted their pricing and it is fair. Thank you for being an honest business! I would return for future smog checks.

I sought a Smog Shop technically capable of performing a State-mandated Smog Test on my 1995 Buick…read moreRoadmaster Estate Wagon. 1 shop had broken equipment and a 2nd couldn't do "a classic car". Crescent immediately made me feel welcome as I walked in and responded "certainly" to my enquiry. I was 2nd in line. Parking is awkward - initially park in the first lot fronting 6th St., then walk in. The test is complex but was performed well. No grease, no dirt, no fingerprints! The Shop Owner keeps you apprised of the test progress and really simplified the paperwork. It is easy to see why the shop floor is busy. Technically competent with knowledgeable staff and a professional atmosphere! Once found, you'll be pleased! (I'ld like to see a Vending Machine w/Diet Coke). They do offer a wide range of mechanical services and work to ensure you understand choices and options. It is no wonder they are crowded! A very worthwhile experience!!

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.
