Washington always had a 25-year law anyways and now any vehicle that's a 1995 or newer has catastrophic converters and check engine lights and stuff like that so there's self regulated.. likely 95% of the cars that came through Washington DEQ hours were passing anyways.. in Oregon if your car is a 1975 or newer and has to pass DEQ so they have 20 years of older cars trying to pass DEQ... Are still finding a way to make money off of it...
