I guess your just going to have to ask the previous owner lol. Found out that my car has had 3 owners. (including me) I'm still trying to fix what the 2nd owner screwed up.
Give your local DMV a call, they might be able to help. I know mine has had at least 3 before me... My dad, My uncle, and Leroy Pickett from Arizona, i have no clue if he was the original owner or not though.
Pretty much impossible to know. I know the history of a couple of my Mavericks back to the day they rolled off the lot new, but all I know about the '72 I drive every day is it's originally from California (71 DSO), some how ended up in Philadelphia by the late 80's, and it changed hands 4 more times in the 5 years before I bought it, making it's way from Philadelphia to Charlotte in the process. I'd love to know more history on the car considering how much I've driven it. Going to get a Marti report on it one of these days to at least see what dealer it came from.
