A Gumpert!
Why is this thread just turning into ppl naming ridiculous cars.
its completely different, might as well ask people what kind of plane they would trade their boat for.
Smart car with a Busa motor (1397cc and a 9 mill billet crank). Or Campanga T-rex (it does have a steering wheel so its a car IMO)
I traded in my Ducati 848 for an exotic.
