I came here because of Yelp in 2021, I looked up any smog check places that were local and found this one was the best one. I came in as a walk in on a Saturday morning and the gentlemen there assisted me quickly. I was in an out in 5-10 minutes! That is quick. They have a waiting area in their shop so I just waited there and it felt like time went by fast. I'd definitely come back if I ever need to do the smog check again. read more

Montclair Smog Check Center - G&S SMOG - Smog Check Stations Near Me - Montclair, California

Great service, amazing and quick easy smog, AJ and Mo are great and amazing people they know how to do business right

Waited about an hour for NOTHING, sat there for about 30 minutes for the dyno itself to "calibrate" shouldn't the machine be ready before ur customers even get there? Gave me the run around the whole time, blamed his newley installed dyno machine on it sending "vibration so it wasn't fully reading??? Anyways if you want your time wasted this is the place to go. Offered me to come back a different day with a a discount but i will gladly decline this offer. Even if it was a 20 dollar song check still wouldn't take my car back here. Save you time and hassle and take it so there where they know what they are actually doing. Horrible experience read more

Pete was friendly, efficient, and the service was affordable. 100% would recommend and will come again.

Clean fast good price. Came next door to "Bel air Build " for a quick tune up. So 2 birds wit one stone since it's next door in the same lot. In-n-out. HIGHLY recommend read more

Thank you again! read more

Excellent service , honest , professional , and clean testing shop . Great customer service , organized and efficient! read more

Had to get a smog check. Prices are pretty standard so nothing to complain about there. Shop is clean and you get in and out relatively quick. Originally I posted a review about an issue regarding when paying by credit card; it seems however this issue has now been resolved by the owner. That personal accountability is something much appreciated and am happy to edit my review and give this place a full 5 stars. Again, this place was quick and easy, everything was probably 15-20min tops and I was able to complete the DMV registration within the next hour or two. My regular smog place is further away so I am happy to find a quality place close by. I would recommend this place to other and plan on coming back for future smog inspection needs. Thanks for your help Mike read more

They were fast and helpful when I had a car alarm issue not even relating to the smog test. Super nice!

Clean shop. Nice guy. Quick. Honest. There is a large window so the test can be observed. He explained why it costs more for older vehicles to he tested. He gave me a discount ... just because. I came way out of my way to be tested here. He was recommended by a competitor whose equipment was out of commission. If a competitor recommended a shop, that's a good sign. read more
