The staff were very professional, and the shop was clean and well organized.

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.

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 went in for my usual Mobil 1 oil change that has normally cost me $89.95, only to suddenly be charged $130 -- over a $40 increase. I was told the price jump was due to the war and increased oil costs. Wanting to verify that, I called three local auto parts stores afterward, and all confirmed that oil prices had gone up only about $1 per quart. For a 6-quart oil change, that's nowhere near the extra $40 I was charged. To be fair, the service itself was still quick and efficient as usual. But using current world events as justification for what feels like excessive up charging doesn't sit right with me. Loyal customers deserve honesty and fair pricing.
