Given that some of these cars have changed hands 3-4 (or more) times in 25+ years, I think it's next to impossible to state that paint is 100% original if repair work was done out of pocket and done well if previous owner(s) did not disclose it.

My car, for example, had some hideous aftermarket wing put on by its original owner and it was replaced with a repainted "original" deck lid like the one it came with from the factory. I only knew this because the person I bought it from disclosed it. Had I not been told, I would have assumed my car was 100% original.
