The wild card in such speculation is always going to be world political/financial climates as well....I'm drawn to an article that recently appeared in Hemmings Muscle Machines that had a very interesting take on the winged-car hobby: They said that (in general) people who want, and can afford, a Superbird probably already have one. So the 'Birds that fetch the most at auctions are the ones where someone is looking to step up to a nicer example for their collection.
So if that is true/accurate, the consigner better hope that this 'Bird is nicer than one already in the hands of a collector if they want to get top-dollar for it.
Theres alot of those types of auctions up here. I stay clear from those.I'd rather have the '68 Charger... but I already have a Copper car. Online auction, can't see it bringing the same bucks as live and note the car locations if you wanna buy. They're not at the auction house, they're still sitting at the sellers locations which I can see going wrong in many ways. It was enough of a cluster f live in Mississauga when a car would be sold only to realize they weren't holding the original ownership to transfer..
