What Our Clients Say About Us

“Every time I need a smog this is where I bring my car. The staff is very friendly and honest. I have been in the waiting room and have herd the tech come tell the customer from his visual inspection he didn't think the car would pass and they should have their car serviced. I would recommend taking your car here if in need of a smog test.”
