Had my car in for a smog check. All pass but one...timing was off by 15 degrees. You must have car fixed in shop in order to avoid having to pay for the test again...unlike other smog test sites that allow a second after fixing problem. For $65 + tax they will adjust. With a wrench they adjusted and corrected - 5 min. total
Pros: nearest $10 coupon off smog test
Cons: long wait
