Advance Smog Auto Care Center

Fast service, got me in same-day for a smog on our old truck, and the whole thing barely took 30 minutes. Great pricing, great customer service, highly recommend.

Advance Smog in Rohnert Park is the only place I'll take my car for smog checks and repairs. The owners, Kelvin and Tran Li are good, honest and very kind people with the best prices in town!

I took my Acura here to SMOG before selling it to a private party, sure that it would pass, as it always had. Failed. Apparently if your battery dies (which mine did) it resets an error code that requires driving up to 60 miles to reset. With this advice, I took it to Petaluma and back, and what do you know? Passed!! Their advice was spot on and they helped me get it passed so I could pass it on!! Check them out!!

Receptionist was super nice, and knowledgeable. I was in and out in about a 15 min. Fastest smog I have ever had.

They are the fastest smog shop I've used. The lady at the front desk is super nice and makes sure you have everything you need for DMV

Everyone here was so nice and helpful! I've never before been to any vehicle service center where I felt so welcome and cared for. They were honest about what was going on with my car and what I would need done but that I won't need it any time soon. I appreciate such honesty. I'll definitely be returning in the future!

Kelvin and his family provide a great service as a small business me and my family have been their customers for 20+ years

A great mechanic, and a clean facility. Calvin always fixes everything right the first time, stays in close communication with the progress, and is very honest. I never need to worry about getting ripped off. I highly recommend this business.

Easy and convenient. The family fun business is very professional and customer service focused. Really appreciate the work they have done on my and my husband's vehicles.

I've taken 3 cars and a motorhome to them. Starting at the front desk and to the garage it has been consistently a friendly experience. Whether I passed or not they had suggestions on where to get what I needed if I did. They are fast too with a comfortable waiting room.

The best smog around. They are so nice and so fast!!

Very quick and reasonable price for smog check.

I went here for my (super last minute) smog check, and they were amazing! They got me in and finished inside of 20 minutes, even though I didn't have an appointment, and sent the results electronically to the DMV.

(I also had my dog with me, and was able to bring him in while I checked in and while I paid. We went for a walk while they were taking care of my car.)

Pricing was pretty good, too (less than $60). I definitely recommend them for smog testing!

Very nice people and excellent service. Their bays are so clean, you can eat off their floor (but I won't). :)

This place is fast, friendly, and honest. You couldn't ask for a better smog shop.

HIGHLY RECOMMENDED: Kelvin does quality work for an honest price. He has done smog checks on my vehicles for about 10 yrs and he is now doing some minor repairs since I no longer have the time. I have considerable experience working on vehicles (engines, trans, suspensions, electrical, etc), so I am a pretty good judge of what is and what is not a fair estimate.

I come to Kelvin because I trust him to be honest with me. Other mechanics will take your money & tell you they can fix anything but they won't tell you when a car is a lost cause. Thanks to Kelvin I traded my old Malibu in for a Toyota and I couldn't be happier. The girl at the front desk is always friendly and polite. I won't be looking around for another mechanic for a long time.

Hands down the best!!! Their service is excellent. Their waiting room is very nice and relaxing. They even have a large air purifier. The best you can ask for in these scary times or at anytime!

Amazing operation.

Made an appointment for 1:45pm. Arrived 5 minutes early. Left @ 1:55pm with Smog Certificate complete and sent to DMV electronically.

What's more: I've gone here since the 80's although there has been a Management change during that time, the service is the same...courteous, utterly reliable, quick and priced right.

What more could you ask?

Easiest smog check I've ever had! Called for an appt. and got in 30 min later. Was outta there in under 20 min. Fast and friendly service and very reasonably priced. I highly recommend this shop and I'll use them again.
