I just recently purchased a 56, and along with it came a whole pile of documents, most from the complete restoration the previous owner did in 1997. Also included was the original factory invoice , the checks he had written to the previous owner (who was a friend of his) in 97, *and* the last CA registration and title transfer from the original owner (registration shows original purchase date). So as the 4th owner, I have the names of and addresses (at the time) of all 3 previous owners! It's really neat, and I lucked out to get this info, thanks to the folks who cared for her before me 🙂.
Owner 1: 1956-1979
Owner 2: 1979-1997
Owner 3: 1997-2021
Me: 2021-present
(I don't want to post the names here, as some folks prefer internet privacy).
Funny thing is that the original owner lived quite close to where I live in CA, then the car went to Illinois, then to Arizona and ended up back here in California 🙂.
