I agree with much that has been said, but not all. Documents and pedigree are your safest bet but they're not the only game in town. Other wise how do you account for the ZL-1 powered Camaros I build selling for 90-95K. All in less than two weeks and some in less than 2 days. I can assure you my customers are not suckers and all have extensive numbers matching, documented collections. Including real ZL-1's and crossram Z's. I'm told the cars are a perfect fit for them because they get the look and the feel with out the risk. It's to risky, in some collectors minds to take a numbers matching ZL-1 or crossram Z out on Saturday and spank it. But I know for a fact that my cars get driven like they stole'em. I hope that trend continues because I've got a Christmas model coming out. Did I say I hope that trend continues.....I hope....I hope....I hope.
