I received a PM from a person wanting to purchase anything off of a car I scrapped that had a sticker or tag claiming that was all he needed to reproduce the car. We've discussed this on the forum and concur it may very well be a federal offense. The act of vin swapping and forging a title and tags is one thing. Selling a special car to someone else without disclosing the fact that the only real part is the federal emission tag is not only illegal but highly unethical. My caution is not only to beware who you sell to but also who you buy from.
