Cobras generally don't sell well at BJ. Last year was all hyped up fo course, so 3015 and 3301 sold well. But forget selling replicas or continuation cars there, they never bring any decent money.
I think the problem with Cobras, is that you don't get the "hype" bidders. In a room full of drunk millionares, you can bet every one of them knows what a Hemi Cuda is, or what a Boss 429 is, but really, only people INTO Cobras know much about them. So that dude with a lot of cash that may have missed out on an earlier car he wanted, would have no problem impulse bidding on a Hemi cuda. But put a replica Cobra on stage, and forget it. It's no different that the dozens of street rods or customs that crossed the stage (and also didn't sell for crap). And a continuation car is no different. They don't know what they are either, especially with a more "grey" explaination.
I bet the guy with that FIA is still kicking himself. He had to lose his shirt big time on that car.
