When it comes to rare Porsches, there are several. Cars like the 935, the 356 America Roadster, the 991 Club Coupe, the 1967 911 R, and other various factory-built rarities. But since it's the holiday and I am a committee of one when it comes to voting, I thought I'd talk about the mid-engined, very, very limited edition of the 914. It was known at the Porsche factory as the 914/S, but you may know it by its more common name, the 914/8.
