In my state, North Carolina, they heavily scrutinize and research classic cars being registered in the state coming from outside the state. There have been serious issues with people faking high value classic cars where there were plentiful models with regular options but few or special order only models for racing and such that now are very rare. People build and fake the plain ones to appear as the rare ones and the crime in that is not the modification as you can modify the cars but the crime is that they change and fake the VIN or Commission tags or buy just the title and tags off wrecked or beyond repair cars. The misrepresentation is the fraud. They make very hard to catch clones…you pay $100K for a 70 Challenger with a factory shaker hood and hemi with a four speed and all the numbers match but actually when it started life it was and automatic six cyl family model that would go for $20K now. Other states have easy registration processes that almost facilitate the misrepresentation and the bad guys use those states to launder the cars. Anyway our highway patrol (State Police) are strict in reviewing older classic type cars for hints of misrepresentation malfeasance. It took 4 months to get my TR4 ok’d and it was a clean commission tag and had a solid title from neighbor state, Virginia, where they are not pushovers. I want to be sure there is no chance I have pieces of someone’s stolen car or vice versa before I put money into a restoration and have the State Police tell me it can’t be put on the road.
