Help... Vin #'s dont match

I learned a lot in this thread....I think.Never did I think that if I had a legal title to a car then changed the core support and package tray without getting some government agency involved I would possibly no longer have a "legal" car and title.
Really, the whole issue is that a title is a simple peice of paper, and if you have that VIN tag from a car that goes with the paperwork, you could steal a nice car, install your VIN tag and if everyone veiwed it like most on here, it would be "no problem" Thats why there are laws on the books. The OP was sort of takin, partialy by his own lack of research, but its sad that people think deception is ok..........bassically my whole point.
