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.

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!
