Testimonials

HEAR FROM OUR CUSTOMERS

Fast and friendly service A+. When I first walked in I was promptly greeted which was nice. Overall inside was nice and clean with AC on. I was explained the total cost out the door with everything included. Eventhough all the prices were posted on a big information board right on the wall I did appreciate the extra step and explaining everything. Took a total of 20min and I was out the door(only because there was a customer ahead of me) so not bad at all. Price was very competitive compared to the other Smog places in Antioch. I would Definitely come back again.
Cajun C.
Awesome Pricing for a SMOG with CERT. sitting area was nice with water and snacks (gummy bears and chips). Front desk worker was friendly and kept it 100 with everyone who came in.
Jesse C.
In-and-out in a 1/2 an hour . The gentleman was very professional and took great Care of my vehicle
Frank Griego
Great and fast service, unlike other places they take the time to check your vehicles monitors and let you know if it will pass before they connect it to the smog machine. If the monitors aren't ready to go they simply tell you to keep running the car at no cost ! highly recommend them
Luis R.
Great smog place. Quick and honest service for a great price. If you pay cash you get $2 off the total which is mostly about $40 for my 2000 Corolla and 2010 Altima Hybrid.
