Always been my point with '55-57 Chevy's, Camaros, most any Chevy really, Mustangs.... They were the most common and plentiful cars around, yet are some of the most valuable. Certainly not because of rarity. In the case of cars, so many had them and want them again. Not to mention having so many was kind of like additional free advertising. Obviously all those cars did look good and gained a huge following. At some level everything is a bit of a "monkey see, monkey do thing" I suppose. One guy has an AMX, now every body wants an AMX!

Everybody should want an AMX by the way.
And, you rightly hit the 15 bazillion page mark for us!
