Customer Reviews

Trusted by Drivers Across Marin County

“This was the best smog experience I’ve had in recent memory. I was in and out in perhaps 15 minutes, much shorter than I anticipated. The waiting room was clean, and the attendant was efficient and friendly.”

Bianca Mascorro

“This place is one of the most affordable smog check centers in Marin. Although I live in Mill Valley, I drove here and was in and out quickly. The owners were incredibly friendly, and I even had my VIN verified here since I had to smog two different vehicles. The service was excellent, and the staff was very attentive. What makes this place even better is that it’s also a gas station, convenience store, and has bathrooms and a nice waiting room with a TV. It’s a great place to stop for a quick smog check and get some supplies. I had a really great experience and will definitely be returning.”

Kenia Sciarrilli

“Another happy customer. They smogged my 1998 Toyota Camry (which I believe requires a special machine that many places don’t have). No wait, no hassles, fair price. I will be using them again.”

Binthair Dunthat

“Friendly, fast, efficient, and a very clean shop and waiting area. Brought my car in for smog today and there were two cars ahead of mine, and even with that, I was in and out in 30 minutes. $65 out the door, better price than most in the area. Highly recommended.”
