I had to have my Smog done and it was late in the afternoon. I called and spoke to a very friendly…read moregentleman who explained what to consider for my car which recently had an engine replacement. I had never known about Drive cycle and he shared that if my car had not completed that, some cars have not passed. He recommended I contact the dealership that replaced my engine to verify before bringing my car! He told me pricing with my coupon and the exact price I'd pay. I was able to get there before closing at 5 pm, have my car smogged in less than 10 minutes and on my way! He was very kind and efficient and even knew AAA's hours and that my Smog would be in their system when I arrived! I will be back next time.

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.

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).
