I needed to get an emissions test prior to registering my car in California (moving here from Colorado). This place was open on Sunday and I had the testing and paperwork done within 20 minutes. The price was competitive (I used a $10 off coupon from Yelp) and the staff was friendly. There's a small additional charge for the Low Pressure Fuel Evaporative Test (LPFET) for any vehicles manufactured before 1996. If you're worried about your vehicle passing, it can help to drive it around prior to getting it tested (the re-test fee is $35). If you need a smog test, I'd definitely recommend checking this place out.
