You have to look at it two ways , those looking to buy a GNX , don't want them to be up , those with them , of course want them to be up.
I think the Toy Barn 362 mile X @ $150k + the $15k commission was a fluke , that was absolutely crazy money for one , and was a case of two individuals who put up their fists with $$$$$ . Example , X #496 with 110 miles (and no riveted molding) only hammered at $100k I believe only two weeks after Toy Barn X.
Those who paid these prices , you obviously are into collector cars , know what you want, and with that said , you couldn't open up the computer and see the handfull for sale at places like Carsonline , Hemmings , or even Ebay ?
I truly believe selling a car at a BJ , or Mecum , or any of those auctions is a risk . I myself would never do so , if your car is worthy , it will sell itself on the sites I mentioned , no travel fees , missed time from work , hotels , entrance fees , commissions , etc. If you want the kind of price that came from a car that crossed the block , go there and do so (or try) , but don't be disappointed when it doesn't "hit" the number .
