So....What is YOUR opinion on VIN swaps ?

I see this becoming a hot topic again. Some people that I respect seem to have no problem with it but it rubs me the wrong way. They claim that they are not doing it to cars that will be misrepresented or sold but what happens in the future? Owners die, cars get sold and new owners may be thinking that they have a legitimate title and history when they have a fake.
Nobody that I have known has done this to any Hemi or 440-6 car. I'm talking about regular enthusiasts with cheaper A body cars.
One guy claimed to have a car that was too rusty to save but had current registration. He bought another car from a junkyard that wouldn't give him a title.
Another likes to buy 1974-76 Dusters and Dart Sports to convert to 70-71 Dusters and 71 Demons.
I have some experience with metalwork. It isn't hard to cut out numbers and patch them into another car place. My understanding is that ANY tampering with a VIN is a federal offense. What about the people with E body cars that get their dash pad restored? The VIN tag gets removed for that kind of work.
I have owned cars that I bought without a title. In this regulation rich climate of California, it isn't that difficult to get a title. Even if you get a car that has no VIN, the state issues an alternate VIN that is attached somewhere else.
Kern, maybe the rules have changed, used to be a law, a legal business( i.e. a body shop, or a collision repair center...) was the only ones allowed to legally change a VIN... As far as I still know, the CHP( or the DMV..) needs to do , an physical inspection. My '98 Taurus was totalled out, with 86 k on the odo, I had to do a lamp/ brake/ smog cert trio, had an actual DMV employee do their job, and check the VIN...
I understand completely, your thoughts on effects,on the hobby. Someone tried to sell me a 69 Camaro as a SS, when it was a basic sport coupe. And I worry about that ,too... It's why I buy Scamps, Dart / 6 models, to hot rod.
