Last year I went to the Mustang Owners museum in North Carolina. All of the mustangs there are either the museum owners personal stock, or lent by mustang owners around the US. Stock changes every 6 months or so and they even have one of the oldest (by VIN that weren’t showcase preproduction) mustangs as a “barn find”. 
The people that run it are obviously knowledgeable and were a blast to talk to. When I went they mentioned that they were trying to acquire the full scale clay S550 model. It’s possible that it would have been the one that was used in the documentary “A Faster Horse”.
God damn, that’s a beautiful car
Definitely trying to pump the numbers up here! Almost seems like everyone likes the older classics.
Personally I like a whole lot of stuff, but the older classics are easy for folks to appreciate, so they’re a great choice! Your contributions are appreciated!
