One of just 97 examples ever built, this 1955 Porsche 550 Spyder is an outstanding example of one of Stuttgart's best rides. The 550 was introduced at the 1953 Paris Auto Show and was soon after nicknamed "Giant Killer" for its ability to defeat its more powerful track rivals. This particular example is chassis 550-0050 and was delivered new to the US west coast with a silver exterior and black interior. Given a full restoration in the late '80s, it was later purchased by Pablo Picasso's son Claude, who raced it in the Targa Florio historic race and the first Le Mans Classic edition before selling the car himself. Accompanied by extensive paper history, it's a fantastic chance to own one of Porsche's most desirable models.
