I wonder if You could make a tribute car and amazingly "Find" the lost black one!!
Oh of course, it would have to get a "warrantee" block 'wink wink" and a few other things
a few sloppy number stamps, all screwed up on the assembly line ..of course!!!

Basically, anytime anyone wants information, for no apparent reason, it makes everyone else wonder why? So any knowledge is better kept secret.
"Thanks" to all the crooked dealers, flippers, auctioneers, and so forth, for driving all the prices up, building clones, faking numbers etc...etc....
