I just took my 96 Acura Integra and it failed smog for high nox? I heard this is a good place from a friend. But service did not seem welcoming and I am not sure if smog standards have changed over the years but I failed this time and I have never failed before in 15 years. The tech did not check tire pressure which affects tests and I actually had too much air in the tires(I checked when I got home). I also should of gotten the cats hot before going in, that is my fault as well but the tech never gave a heads up of that in which I would of listened and most times they do. Overall I am not sure I will go back given that a retest is $80 in which I never heard of that before. My regular shop charges about 20 to 30 for a retest which is closed on weekends. So not sure what to do next. Any id

Shawn was honest and informative and the prices were very reasonable. He was quick and even helped with DMV paperwork. Will go back here every year! - Teresa

Well-priced smog in the area. The smog place I normally go to wasn’t open when they should’ve been, so I decided to check this place out instead. They have nature documentaries playing and an arcade machine to pass the time, although it won’t be long to finish a smog. Also, it looks like the owner is an anime fan haha. The person working was friendly and even told me about an issue in my hood, and tried to fix it for me! Also, You can pull up a coupon on their website to get some money off your smog. Also it’s $20 for a retest. I definitely recommend this place!
