That statute, of course applies to attempted falsification. If you legally own both vehicles in question, and apprise your local DMV of your intentions beforehand, this a perfectly legitimate procedure. Happens all the time.
The following is just my opinion. I am not a lawyer.
I would NEVER do this but if I was to consider it - I would consult an attorney and get everything in writing. I would think it is highly illegal. They call the shops that do this "chop shops". Because they cut up; chop, one car to make it look like another. Individuals that do it are just as illegal.
If it "happens all the time" - why do you never hear anyone identifying this when a car is sold?????????? Buyers be VERY aware!!!
This is one of the most damaging practices in the classic car industry today. Personally, I feel there is too much opportunity to defraud when this takes place.
What if the current owner of both vehicles decides to sell? To get the most money out of the re-bodied rare car - there would be tons of pressure to not disclose. And then if the car changes hands a few times the history of this VIN swap is lost. Then what if the other front fender support with the correct VIN for the rare car is found - someone tries to sell it as rare. Now you have some serious trouble. And while this last scenario would be not-too-common, it could happen.
If the VIN doesn't match the body (under fender support stamping) the the car has been altered and needs to be thoroughly documented. And then if those numbers do not match the motor and transmission - it is NOT a "numbers matching" car. It is really that simple.
This and similar activity are what make lower-mileage, one or few-owner cars so valuable.
