Store hours and phone number.
Linda C.

I showed up about 5:45pm in my 2002 Xterra so I could check out the business hours. I figured they were open until 5pm but wanted to verify and grab the number. While I was taking the info down, Quinn, got out of his truck and opened up for me. I told him it was ok and I could come back during regular business hours, but he insisted and said "you're already here." I was in awe. Excellent and superb service. So generous and accommodating. Friendly guy. Affordable pricing. He was already in his truck to go home, but he chose to help a customer instead. These qualities are so hard to find nowadays so I sincerely appreciate that he took the time when he didn't have to. I HIGHLY recommend this place. I will be a loyal customer and refer everyone I can to him.

Scam Business. I was told I failed after he took my card and charged. That is shady practice. Do not recommend.

New person in shop now seems to create a fail by revving engine in low gear. Other clients also were needing $50 "retests".

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 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.
