Great Place. Free retest $50 test $9 certificate! Definitely reccomend the tech is good ppl. Dont judge a book by its cover 100% recommend I SAY!!

Lok was a very nice and innocent man, he is very professional and knows what he is doing, he helped me with my car when a small little coolant hose burst, he makes your day and is very kind, i 100% recommend going here.

The best place to smog your car in the Bay Area! Great customer service, Ill never go anywhere else!

Under New Management. Great people and Service

These guys truly saved me!! I highly recommend this place for anybody who needs smog test. I recently moved to the area and had to do the smog test for car registration. The other place I went to told me that I didnt pass the catalyst monitor and had to drive 90 miles above 55mph with no AC, nonstop and come back. For any retesting they were going to charge me additional smog test fee. When I brought my car here instead the guys were super nice and kind and most importantly honest. Even after driving almost 100 miles my car was not passing catalyst monitor. They told me I can look into the specifics related to my car model to pass the catalyst test and they were not going to charge me at all until I pass the smog test with unlimited number of retesting if needed. Instead of wasting my time and money away, I was be able to bring my car back for a retest after a short drive (few minutes on highway and city driving mix) and I PASSED!!! It can be stressful to go through this without having clear criteria, or idea of how much time or mileage or money it takes. I feel so fortunate to find them! Moreover, they even offered a bottle of cold water when I returned after driving without AC to meet catalyst testing.

Smog tech was super Fast and Friendly. Manager gave me a great deal. All staff was very nice. They gave me a complimentary water while I waited. I was in and out in 15 minutes after pulling my car in. Very professional, did things as they should. Would reccomend to others.

I took my 1991 Ford Mustang to Concord Smog & Gas for its checkup. An excellent and affordable place to have the smog test done! The technician is very knowledgeable about this old auto, and he is very thorough. The owner is friendly and hospitable. They even built a nice waiting room onto this shop. Ill be there again for the next smog test, and I look forward to buying gas at this location. Great!

Good service but busy. Better to make an appointment.

Smoke check is done ✔But mechanic are looking everywhere, he parting out the engine trying to find something. It looks like he wanted to break something. I would not recommend it. It was the first Smoke check very picky.

Fast, easy, reasonably priced

Outstanding customer service and pricing. Got my smog check in less than 20 minutes

Most affordable smog I could find in the neighborhood due to the good sale. Very fast and friendly service. Ill definitely be taking my other vehicles here for smog from now on :)

They were amazing!! Good prices, great work and great attitudes. Definitely coming here from now on!! Thank you guys.

Did handyman service of power washing entire station concrete and asphalt and owner refuses to pay me. Am filing a small claims dispute over his hot head. What a peasant move, and I have an 8 week old infant baby and he knows this. 30 hours is enough to complain about.

A SMOG check is a SMOG check, and that part is uniform. What helps this place stand out is a) the temperament of the guy who does the SMOG check, and b) proximity to my house. The young man who performs the SMOG check is very amiable, approachable, and will engage in conversation with you regarding what needs to be done, or about how well your vehicle did. Pretty easy-going, good guy!

Great customer service! Answered all my questions, was quick, efficient and very pleasant! Highly recommend for smog check!
