Porsche introduced the Targa in 1967 with a soft, removable rear window. These cars have become coveted for both their rarity and the open top driving experience. This just happened to be the same year Porsche unleashed its new 2.0-liter 911S on the unsuspecting sports car world. Both the soft window and the 911S are rare in there own right, but when combined, they become the stuff 911 legends are made of.
