Auto shows, including the Chicago Auto Show, are all about concepts that may never see the light of day. And as important as some are in setting the direction for a company's design language or technology, some are just completely ridiculous. In honor of the ridiculous, we're curious to hear what concept car you'd like to see get built. From any generation. Turbine-powered Olds? Why the hell not? Isuzu Amphicar. That's the ticket. Shock us with what you remember.

What is the concept car you'd like to see built?
