Typically these auctions for Barrett Jackson have brought between 300-500k depending on the car (first ZR1, first 60th anniversary 427 Corvette Convertible, first GT-500, etc.) so I wouldn't be surprised if it went somewhere in that range. Remember not only is this for the first Viper but it is a charity auction, which normally results in people throwing insane money at it because it is a tax write-off. The only thing holding this auction back is that it is the Orange County auction and not the flagship Scottsdale.
