Client Testimonials

Searched all over town for a smog check station open on a Sunday. This one is it! Service was fast (15 minutes) and very friendly! Waiting area inside the store is very clean and organized with a nice collection of Hot Wheels on display only with some for sale on a rack by the window! They obviously love their job and take pride in the work they do here. I'll be coming back next week to service my other car.

Tip: They charge a small fee if paying by credit card so make sure to bring cash to save money. I also used the $15 off Yelp check-in coupon to save even more!

I was able to go in for a smog check on short notice, and was out of there in under 20 minutes. Be sure to use the Yelp check-in discount!

Very enjoyable experience & made getting a smog check painless, all my friends and I come to this place. They have parking in the back, a nice wait area, and he even gave me great referrals for muffler places in the valley. Overall great value & great service. There's also a really good crepe place next door!

Great shop, friendly, professional and quality service!! And also a very nice waiting room..Will definitely make this my go to shop.

Just had a smog check done here. Super fast and easy. Clean waiting area and friendly staff. Will be going back to have my wife's car done next month.

Sam is a very friendly and professional person. After the smog check on my own car, I came back another day for another vehicle. He helped us figure out exactly what was going on with the car and gave us recommendations for how to move forward. I will be recommending this place to anyone and everyone!
