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.

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.
