The Holy Grail of Stuttgart. The car that killed James Dean. The giant-killer. Porsche's 550 RS Spyder is the most sought-after car to come out of the Porsche factory, and the car that helped launch Porsche's legacy as one of the winningest car makers ever. Only 90 550 RS Spyders were made over three years, and one unnamed collector has decided to part with theirs, giving someone the opportunity of a lifetime. Details are sparse, but the car looks to be in unsurprisingly immaculate condition, original, and undamaged. If your pockets are deep enough, this is a rare opportunity to add a crown jewel to any Porsche collection.
