The 1983 Frankfurt Motor Show was chosen for the unveiling of the Porsche Group B prototype. Even in the closing hours of October 9, finishing touches were being applied to the car to go on display the next morning. After the first two prototypes, the bodywork was modified to include air vents in the front and rear wheel housings, as well as intake holes behind the doors. The first prototype receiving those modifications was code named “F3”, and was destroyed in the first crash test.
The road version of the 959 debuted at the 1985 Frankfurt Motor Show as a 1986 model, but numerous issues delayed production by more than a year. The car was manufactured in two levels of trim, “Sport” and “Komfort”, corresponding to the trim with more creature comforts and a more track focused trim. First customer deliveries of the 959 street variant began in 1987, and the car debuted at a cost of DM431,550 (US$225,000) each, still less than half what it cost Porsche to build each car. Production ended in 1988 with 292 cars completed. In total, 337 cars were built, including 37 prototypes and pre-production models. At least one 959 and one 961 remain in the Porsche historic hall in Stuttgart, Germany.
In 1992/1993, Porsche built eight more cars assembled from spare parts from the inventory at the manufacturing site in Zuffenhausen. All eight were “Komfort” versions: four in red and four in silver. These cars were much more expensive (DM 747,500) than the earlier ones. The later cars also featured a newly developed speed-sensitive damper system. The cars were sold to selected collectors after being driven by works personnel for some timeand are today by far the most sought-after 959 models.
