The US Customs guys are not stupid. Not all at the same time anyway. IF they decide to investigate, they will scrutinise it very carefully and they WILL figure out that it's not a USDM car.

From what I've read, they would impound and dispose of the car. Depending on the circumstances, the owner might get away with just a slap on the wrist (apart from the loss of the car).

But if the owner has tried to cover up by tampering with the VIN, falsifying documents etc, they would end up in a lot more trouble.

Better to keep the car untampered IMHO. Most importantly, don't give the authorities any reason to investigate. Keep it under wraps and pretend it doesn't exist.
