Just as a barely related note
Years ago I bought a 65 fastback with the DSO of 710001. First special order car in southern calif. Always figure the dealer did the order just to get one of the first fastbacks produced (move to the front of the line)
No blank paint code (blue on blue car) , 6 cylinder, automatic with nothing ( that I could ever find) that made it unusual - other than the compass option that had likely been added at the dealer
Only had it for a few weeks before I cut it into pieces
