I'm always curious to learn the backstory of how these cars get mis-identified. While I understand that there is some outright fraud that can happen, there are often cases of simple mistakes that were made ... oral history can become its own living entity that may not align with the facts and so on. I'd be interested to learn how long the current owner/seller has had the car and why, exactly, he believes it to be an original Z28. Perhaps someone dropped a 302 into it at some point? It doesn't, of course, change any of the facts.
