Saab Aero X Concept
It was crafted in the not-so-distant past, when Saab still had access to the GM parts bin. The stunning Saab Aero-X concept lifted Corvette chassis bits and stuffed in a twin-turbo V-6 when it bowed at the 2006. And then it kept showing up to auto shows long after its name was removed from the VIP list. Saab's transition into Spykerdom now complete, there's new talk of building the look on a C8 Aileron chassis, but those rumors are largely the work of Spyker CEO Victor Muller.
2000 Jaguar F-type
What better way to show off Ford's mastery of the Jaguar domain, than with a new E-Type successor? The cleverly named F-Type hit Detroit like the blizzard of the year before in 2000, and everyone in the exceedingly cramped rotunda built inside Cobo Hall was convinced it was headed for production. Sister site TheCarConnection even called the F-Type a concept that should have been built. It's 2010 now, and...um...where's our F-Type? New Jaguar owners Tata are hinting at a new sportscar slotted below the XK, but...stop us if you've heard that one before. No, really, make us stop.
