IMHFO it comes down to there are far more people, willing to spend more money on Chevy's & they always have been like that, that's why they sell so damn many of them... As much as I like many GM's, Buicks, Pontiacs & Olds mostly, some select Chevy's... To me it's the followers, the Kool-Aid drinking sheeple mentality, "wanting to have a majority of anything" & to be excepted into the cool crowd, whether they are cool or not... Mega #'s of any year of Mustangs & especially the Millions of 64.5-66's, then GM's tri-5 Bel Airs some early 60's versions too, the 64-67 all the way to 72 Chevelles & then masses of especially 67-69's & even some second gen. 70-73 Camaros, are allover the place... They aren't rare "at all", there were 10's or even 100's of millions made of some models/makes & not in limited #'s at all, like most all/any Mopars of the same era were, that didn't really ever sell as well, because they just weren't as popular... The Mustangs, Chevelles, Bel Airs & especially Camaros, still sell for way over inflated prices... My personal opinion, for way to much money, for such a common car, that was a mass produced car/body style... Maybe it's keeping up with the Jones... I don't get the mentality sometimes, but I do like some of the cars too & have owned quite a few also... But, If it was popular & sold well, when they sold originally, it will always remain popular in the buying publics eyes, that's marketing 101... Some people have more money than brains & the collector car market is far from dead, that auction showed that in the millions of dollars made, for all those rotting hulks... Great for that seller thou....
