Bob, I'm not from PA but a very good friend is. I remember him telling me MANY years ago about the rust inspection thing. Not sure if it's true, but he said he comes from someone getting seriously hurt or died from a rusted out floor in a car or truck. Just what I heard.
I do believe in inspections, but pa sure goes a bit overboard with theirs. And you have to pay for it.
NJ has them which just changed big time a few years ago. (Budget cuts) but they have always been free. Unless you wanted to pay a private shop rather then wait in the lines at inspection stations.
I can understand the rusted floor board thing, but a small rust hole in the quarter panel or a door? I agree that's too far.
I will say when they did emissions here around Cincy, it did take off the road some of those old oil burners you couldn't see as they drove past.
