This vehicle is the first of 59 vehicles that Porsche launched on 28 February 1981 as a small evolutionary series of pure competition cars after the end of production of the 400 road sports car 924 Carrera GT. It is the only white grandprix and the only GTS built in Weissach. All other 58 are uniformly painted Indian red and built in Zuffenhausen. It has the chassis number WPOZZZ93ZBS710001 and the engine number 4710036 and was built in November 1980 as a prototype in the development department. With this model vehicle, the TÜV tests were prepared and the homologation in Group 4 requested. The GTS was offered for the price of 110,000 DM gross. In addition the “Rallye Package II” came with a surcharge of 42,400 DM gross. Each GTS could be approved only with single TÜV acceptance, also only in Germany directly or over customs number. Only left-hand drive vehicles were produced. After 1981, the vehicle was used for testing purposes and for test drives of the dealers, before it was parked at Porsche in Weissach and fell forgotten there for a decade. The Porsche racing mechanic Werner Hillburger rescued the vehicle from scrapping and completely rebuilt it at the beginning of the nineties. The current owner bought the vehicle in March 2007. After a thorough restoration, the vehicle is now fully operational again and is occasionally used at events in Europe.
