    I needed to get a smog check for my car, and stopped in. It was early in the morning so I was probably their first customer of the day and there was no wait. Mr. Mohammed was friendly and quickly inspected my car in about 15 minutes. Save a few bucks and pay with cash and look for the $5 off coupon on their website. Credit cards have a 2.75% surcharge. I paid $53 for my smog check.

    We took our SUV to do smog check and this place is nearby us. We got there around 10:30 a.m. and there were 2 customers ahead of us. It's $58 with certificates (sent to DMV electronically) and I showed the coupon on Yelp and the owner gave us $10 off, $48 out the door. It was fast and easy and we want to support our local business as well. Friendly service and it was done in less than 20 minutes.

    It was a breeze in park, was there no more than 15 minutes. The person was very cordial. I'll def be coming back.

    Are there free retests if the car doesn't pass?

    No! I would take it someone else. He'll make an excuse for a retest which he will charge you more for later. The previous owner was good.

    It was late afternoon instead of early morning like last time but the same quick, efficient, and professional service.

    My car needed both low beams replaced, an oil change and a tune up. Matt was quick to provide me…read morewith a quote that was reasonable. Scheduling the appointment was easy. Brought my car in, went over some paperwork and was told I'd be contacted once the inspection was complete. Sure enough Matt called me to let me know there were some items found during inspection and which ones needed to be addressed right away. After agreeing to the updated quote they got to work. I came back to the shop prior to being told my car was ready, and I think there may have been a delay in getting parts needed (dropped the car off at 9am, wasn't done until 4pm). Other than that, the quoted price is what I paid, there wasn't any pushing to buy a service that wasn't needed. I will definitely be bringing my car back for the additional work needed.

    I requested a quote through Yelp and my request was sent to multiple auto shops. I chose this…read morecompany based on location and called ahead to confirm they could do more than just read basic codes. I had already done my own diagnostics and knew the car was running rich. I had ruled out the upstream O2 sensor, catalytic converter (both new), MAP sensor, and fuel injectors. I explained all of this to Matt before bringing the car in. He assured me they could perform deeper diagnostics with their equipment. After dropping off the car, Matt called and told me they had "confirmed" exactly what I had already told them, and that the next step would be pulling spark plugs--for an additional fee. At that point, I decided to go elsewhere. What I don't understand is why I was still charged the full $85 diagnostic fee, plus a $4 hazardous materials fee and $3 shop supply fee. Plugging a car into a diagnostic scanner does not generate any hazardous waste--no fluids are drained, no chemicals are used, and no parts are replaced. There's nothing about a basic scan that would justify a hazardous materials charge. That kind of fee typically applies when disposing of things like oil, coolant, or other regulated waste, none of which occurred here. In the end, I paid $92, wasted time and gas, and learned nothing new. The most concerning part was Matt admitting he didn't even know spark plugs would need to be checked as part of further diagnosis.
