Fake car at concours? I think I saw one

I went to a concours last weekend and saw a race car that I reported on a couple of years ago, where a mechanic on the car told me it was cut into scrap in the Sixties and buried so the sponsoring automaker wouldn't have to pay customs duties. So when I got home I looked at the program and they still listed it as a 1965 car. i can't call the mechanic, he died. To me it makes the concours fall a little bit in my respect that they got conned. The dying off of the team mecahnics from '65 means there's fewer folks that remember it was buried. I don't want to say what car is is' this is just a cautionary tale about how cars that old can be passed off as fakes when the history is lost...
