A-1 Stop Smog Brentwood

In and out in 10 min, no appointment. Can’t ask for more. A+

Took one of my cars here recently. It was an in & out, wham-​bam, experience,…super fast, maybe 20 minutes tops with one car in front of mine. And best of all my 14 year old battle-​buggie passed the test! This guy is good,. highly recommended!

Brought another vehicle for a Smog Star Station test, took about 45 minutes (this is the longer test for way older vehicles compare to the basic test)
Cool service, was done in pro manner… most likely would recommend to anyone who wants smog done to go here

They are always fast and you don’t need an appointment.

Smog to cars so far quick and if there is a problem he will give good repair suggestion in my case had one car fail. It recently had work dun and the battery
Was disconnected, so that resets the car on board computer he told my to drive it about 50 miles and bring it back so the computer has more time to Make a reading. He was right it passed

Tom took care of us & my son’s car. In and out under 10 mins, this is the place to go! If you’re in Brentwood/​Antioch this is a great deal, especially if you’re military.

I didn’t need to go online or shop around to find a quick and professional smog shop. I called my respected mechanic for a recommendation; he told me where to go.
It’s hard to find, so don’t blink or you’ll pass it, as I did. The owner broke down the charges for me because I asked him why my car is more expensive to smog.

Wouldnt Go anywhere else to get a smog done. His prices are great and he is always quick and professional.

Hands down the best place to get your smog check completed. Always fast and friendly!

I called A-​1 today at 3 pm to get my Suburban smog tested and was told there were a few cars ahead of me and that I should come by a little after 4 pm. So I got there after 4 pm on a Friday and was done & out the door before 5 pm.
That’s what I expect from my Smog place. Thanks Tom

Called them on Thursday and asked when they stop taking smog.. the guy told me 5. I live in Discovery Bay and drove out there just for that. The guy told me if I came I didn’t need an appointment. First.. its in a hard location to find.. no signs clearly marked. 4:45 finally found it and gate was closed! Called several times to find location and see if they were open and no answer. Must have closed early. … wasted gas and time for nothing!

Fast. We bought a 1990 Volvo for our son which needs to be tested at a STAR Smog Station due to it’s age. Total cost out the door $ 70. It was a few dollars cheaper than the major chain oil changers down the road but without the hour wait. This was the second time we used this facility.

Charles and A-​1 has always been a great place to smog my cars. I have been coming back to A-​1 for many years now to smog my vehicles. His doesn’t have the best prices, but you only have to pay $ 20 to do a retest if your vehicles fails smog the first time.

Chuck is great always friendly and fast with fair prices

Every couple years, this place is my friend. Gotta have that CA smog check. I’ve been here a couple times now and need to go back once more in a couple weeks. It’s right on Brentwood Blvd near the Safeway, so it’s easy to find. Keep your eyes open for the big sign and slow down for the one driveway they have.
Prices are average, though I’d love to find a coupon one day. $ 70 for test and cert on my big ol’ truck is ok. So far, it’s never been a long wait here and the service is as quick as I need it to be. The service guys just quietly mosey from here to there going about the task at hand. It’s not a glamorous task nor is it a glamorous place. The job gets done in about 15 minutes, you pay, and it’s done.
I’d recommend smog checks here. Recommended cause I don’t have much to complain about, other than smogging my vehicles every 2 years.
