I've gone here for smog checks multiple times and they are great. Quick service and good pricing. If you fail your smog checks, they will do it again once you fix whatever problems that have caused it to fail. Pete is great! Parking can be tough, but they always find a way to get me seen even if I can't find a spot! I'll continue to come back here if ever I need a smog check read more

Quick service. Used their service a couple times now at a couple of locations. So far so good. Would go again. Recommended by a family member and my friend. 1061-Suite C1 is visible from the street. Use second parking entrance. If you first entrance there is no pathway in back to reach other side of parking lot. read more

My experience was great! Pete is courteous and professional; when it comes to cars, he is an expert at getting to any problems that pop up with your vehicle. I recommend Super Smog Center for repairs and smog service. Pete is very gracious in sharing his time and expertise to help you understand what he is doing and what is needed. Pete's aim is to get you back on the road again. read more

Great Service!!! I was looking for a smog shop to get my car smog so I could sell it. Called this facility to ask if they could do it for me guy answered and said yes come on down... When I showed up he was finishing up a car and being helped right away. Great service ! Fast , Easy& great people that work there. Very outgoing and friendly!! Paid a little less than $49 for the smog. I had a 2004 VW PASSAT GLS Guy was very knowing of his cars so he wasn't a "noob" as some would say. Had me done in less than 30 min. Paper work and everything in had. Smooth transaction! Would recommend to anyone looking for a local smog shop !! They also have a repair shop in the same area with great workers who know what they are doing!! read more

This guy tried to rip me off. I went in for a smog test after replacing the cat. The guy was saying I need to replace the oxygen regulator as well or the car would not pass. My gut was saying he might be lying because he was talking too nice saying he was trying to save me money. I went to another smog station that was TEST ONLY. It passed with no issue. Word of advice, go to a TEST ONLY station that offer no pass, no pay. Don't go here unless you want to fork out more cash to this crook. read more

I have a "newer" car (2017), so it was a bit more, but I was happy to pay for the convenience and great service. There were only three people ahead of me, about a 30-minute wait, and I was in and out quickly. Sergio was amazing... very friendly and attentive. Easy pull-up spot and one of the few places open on a Sunday. Highly recommend.

Their techs spoke Spanish amongst themselves the entire time. I guess my tech assumed I didn't understand what he was saying. He told the other tech that we were ridiculous to watch him because he wasn't going to steal anything. Well, I never thought about that until he mentioned it. I honestly just wanted him to finish so that I can be on my way. I was staring at my car sitting in the stall not doing anything and wondered why I was still there. Another car that came in later was finished first. I told him that I heard and understood what he said. The price for the service was fair but I certainly didn't need the attitude even if it was a joke or not.

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.
