I just purchased a 1971 Dodge Demon from the 81 year old original owner. It is a very untouched lifelong Southern California car with mostly original paint, absolutely zero rust, every receipt since new, cold AC, 318, etc. It is just a really neat car. It is green with a green plaid or houndstooth looking vinyl top. The question that I have is if there is any way to figure out roughly how many were produced like this? I understand that is a long shot of any numbers being broken down far enough to the vinyl top, but I also figured if I could find any help that it would be here. Thank you for any type of information!
