I have failed many a rust bucket for inspection over the years, only to see the vehicle return at some point later on with a sticker on it from some other shop and none of the offending issues repaired. I’ve also been involved in some disputes over failing a vehicle for something , the customer getting very mad , and the state people coming in along with the car in question so ‘we’ could all go over what was failed and why. Sadly, even though I was vindicated in these challenges , the cars still had new stickers on them, and I always asked the state people ‘if I’m correct, the fault is still there, AND it has a fresh sticker on it, are you going to go after the other shop for an improper inspection?’ Never did get straight answers on that question ....
