Original 356 Carrera engine from a Carrera Speedster, removed in early '60s and sitting in a bedroom in Indiana ever since. I assume that the car was wrecked and a total loss. If in fact the car exists, this would be worth a bloody fortune to the current owner.
Just for the fun of it, post your guess as to where the auction ended, $$-wise, before clicking on the link.
