Speedster is a word in the Porsche lexicon that conjures up magical images and, for those lucky enough to have driven one, sensations.

This week in Monterey, a one-off example of 933-generation 911 Speedster is being shown publicly for the first time, a classic design in brilliant yellow built by Milan designer Luca Trazzi and the exclusive Sonderwunsch team at Porsche, based on a 1994 911 Carrera Cabriolet.
