Is this illegal?

I have a friend that has a yard full of old mopars and one of them is a 69 B-body with a fake VIN plate denoting it as a Hemicar. Well one day a few years ago the guys from Graveyard cars stopped by his place to look over his cars for parts or future projects. When they saw that "Hemi car" they got all excited and wanted to know if he would sell it . He told them that the car was the bane of his exhistance and that he was going to chop it up and sell the parts off .... they were freaking out !
