This 1999 Ford Thunderbird prototype is being auctioned off by Barrett-Jackson. It is one of only three prototypes and is the only one that was ever public. It differs from the production models in that it has a one inch longer wheelbase and a more steeply raked windshield. It’s also got a Lincoln V8 and rear wheel drive, for what it’s worth. Not sure what it’ll sell for, but whatever the case I think it’s kinda interesting.
