What if your car is not in the best condition and will possibly fail the test?
Since I'm no longer in CA I will readily admit that I've had more than one sideways smog done. Their rules on things like an intake needing a CARB EO is ridiculous. This is the same state that said the Elantra N has too loud exhaust, stock, even though it meets federal limits. Their BAR inspector ran it in "sport" mode instead of "normal" which is against their policy.
Who, when I was trying to smog my 1986 Dodge Aries, would've been a godsend.
