Since we're dreaming, right, then for me it's gotta be a Mercedes C111
It was to be the replacement for the 300SL Gullwing. Mid engined, Rotary, FAST as F..., a real supercar. Mercedes only built 13 prototypes & pre-production vehicles and then abandioned the project with some being used as test beds for other engines and I think one or two in a museum.
None were sold, despite some pretty tempting offers & requests.
