This place has five stars for a reason! I was in and out before I was able to finish a chapter of my book. Hands down the FASTEST service I've ever experienced. Friendly, efficient, thorough. They had multiple employees ready to jump in to ensure your car is handled with speed. Clean facility. Location is spot on. Anything car related always riddles me with anxiety, but they took the stress out of this. I will drive the extra miles to return here for my smogs. Definitely will be recommending to friends and family members. THANK YOU! read more

It was $73 total in December 2025 with a $15 off coupon. It's near the Auto Center freeway exit, conducive to warming up your engine on the way there. There were 2 cars in front of us when we went, and they still got us out of there quicker than most smog joints. Waiting room is clean, if stark. There's a bathroom if you need it. But man, the music was SO LOUD. Like, the receptionist was yelling over the music, "OKAY, SIGN HERE!" and when she grabbed the remote, I presumed it was to finally turn the music down. Nope. She just changed it from '00s pop to contemporary country. There's an option for a tip at checkout, which always makes things nice and awkward, regardless of tip level. read more

My regular guy was closed yesterday so I tried this place and what a bad experience! It was early morning and the guy inside was rude and obviously didn't want to be there, I asked how much he asked make and model of car I told him and he said $70 which is way more than my regular guy. I was hesitant but I needed it done . When it was time to check out the guy in the office said $75! I told him NO I was told $70 and that's what I'm paying! So I payed the $70 and left! Be Careful! Bait n switch! Will Never return! Very dishonest! read more

I ended up arriving here, due to my first initial stop being closed. Upon walking in the door, it took about a good minute for the guy behind the desk to acknowledge that I was there. Once the service was started on my car, ever owes completed in about 15-20 mins. There was also another young guy working in the shop who briefly kept me informed that my car would be pulled up shortly and we had about a minute concern around the weather that was showing on the television during that time. He then rang me up, explained which copy was mine and how soon they DMV would have the update and said have a nice day. Overall for what I went in for the time of the service was great. The customer service, well that's an area for improvement. But still a place to at least a smog completed. There is a small wait area with a telecast stayed and I did see a sign for a restroom and then another door connecting the shop to the office. Side note: they are located off of a very busy main road ao be cautious of the turn entering into their parking lot read more

Fast, honest, reliable, and reasonable. I took my car in for a smog check and learned that it failed due to a broken air valve. They explained how and what to do to get it fixed and sent me on my way. I returned with the fix complete and smog check was completed. It was an easy process and staff couldn't be friendlier. read more

In and out quick with a low price. They even applied a discount that I wasn't aware of. Significantly cheaper than what I am used to paying elsewhere read more

Fantastic. Went in for a smog and was in and out in less than 15 minutes. Super quick and a nice lobby to wait in while they did the check. They have the stickers too but there was an extra charge for that. If you really need your tags right away it's a good option though instead of dealing with the DMV. 100% will be back. read more

One of the best auto experiences I've had! If you live in Antioch then you know that you don't always have good experiences out and about. Zayed was very professional and helped me through and through, making my experience quick and easy. I was greeted upon entry and given an updates as I waited. This will definitely be my place of choice any time I need a smog! As I sat in the waiting area, I observed many regulars that knew him by name, enter and ask for smogs. The new customers were greeted quickly and when they had questions, were given polite and clear information. Hard to come by these days. If you are looking for a trustworthy place or just plain great service, this is your spot. You won't regret it! read more

I never write reviews but this is the least I can do. I have a 1996 Subaru Legacy. Many smog places turned me away because my OBD2 monitors would say "not ready" no matter how many miles I drove. They know their stuff and found a section on bar.ca.gov website that exempted my car from OBD2 sensor inspection. I only needed tailpipe sample to pass. They took their time on a Sunday (I DM'd them on Instagram) to look this up for me. Thank you for not making me have to throw perfectly good running car away. Other smog places simply turned me away. read more

Great team of individuals and they provide awesome and efficient service. Absolutely recommend friends and family

I have 3 cars from the 80's and as a result I have been to most of the smog stations in the Antioch/Oakley area over the last 7 years. The smog guys locations are by far the best of them all. Was having issues passing my Cadillac recently and both smog techs Alonso and Aaron were very professional and helpful. Their prices are great and come with a free retest. As a mechanic myself I recommend them to all my friends and customers read more
