Help... Vin #'s dont match

For the anti-LE types around here, it's called DOING YOUR JOB. And yes, I have gone over a car, particularly the hot rod/restored types for the very reason this thread was started. As someone mentioned, there's plenty of less-than-honorable types in this hobby and I know it. I also know many don't worry/care about such things but if it was your car that was stolen you'd be screaming & crying to the police to recover your valuable, classic automobile. Unfortunately there aren't too many LEOs that care about this sort of thing despite the value of these cars so that leaves it up to those who know, like me, to be so attentive.
Now if you think all LE has to do is "harass" people you obviously have little regard for LE anyway so your opinion means little if anything. My advice to the OP was simply to help him avoid the very thing some here think is okay (it's not) and to help him insure he doesn't lose his ride or worse, get arrested.
