1995 Porsche 911 Speedster (993)
This car was never produced or sold, and only two units exist. The first one, painted dark green, was offered to Ferdinand Alexander “Butzi” Porsche—grandson of the founder—as a gift for his 60th birthday. The second one, painted silver, was commissioned for comedian and huge Porsche fan Jerry Seinfeld. Obviously, these cars are worth a fortune.
