So quick and easy! $20 off coupon online. I made an appt online, showed up 15 minutes early and I was out of there before my appointment time. I will recommend to anyone needing a smog check.

This place is pricier than other shops. Charged me $68 for a simple smog check after $20 discount coupon for 2016 Toyota sedan. Plus the payment system asks for additional tips. Be aware and ask for total out the door price before purchasing their service.
