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.

Today was no different. I recently bought a used car and needed a smog check for the title transfer. Thankfully, Daren took the time to double-check and realized the vehicle had already been smogged when the previous owner renewed the registration in February. Since smog inspections are valid for 90 days, I was all set! If it weren't for his attention to detail, I would have spent money unnecessarily. Thank you to Daren and the entire team--you guys are the best!

I typically rely on Yelp to vet a business's reputation before visiting, and in hindsight, I regret…read morenot reviewing the feedback for this establishment sooner. I visited this location for a smog check, only to experience the exact issues previously highlighted by other customers. If you filter the one-star reviews for "front desk" or "Nicole," a clear and troubling pattern emerges. It is disappointing to confirm that these accounts are accurate. The issues I encountered include: Unprofessional Conduct: Nicole was dismissive and remarkably rude. When I attempted to discuss the service, she was entirely unwilling to listen or provide basic professional courtesy. Pricing Discrepancies: There was a blatant refusal to honor the original price quoted. She insisted on overcharging me, disregarding the initial agreement. What is most concerning is that the owner, Julie, appears to be aware of these recurring complaints, as she frequently responds to negative feedback. However, the fact that these specific behavioral and billing issues persist suggests a lack of corrective action. As a consumer, I believe a business is only as good as its management's willingness to address systemic problems. Based on my experience and the history of similar complaints, this business really got some serious problem. Also, if you live around the Chino / Chino Hills area and see this Nicole lady, please avoid her at all cost.

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!

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.
