In 1978, Porsche began the “Sonderwunsch” program, which modified production cars into unique cars. One of the examples is this 1989 Porsche 928 GT Flachbau, which four months ago was featured in a six-page Porsche Fahrer feature, outlining the unique and special qualities of this rare car. It is now up for auction.

The car was bought new, and then the owner handed it over to the experts of the Porsche Exclusive Department, who turned it into a unique car. It is equipped with covered pop-up headlights (option “XA2”) replacing circular lights, wider body skirts (option “XB2”), wider rear wheel arches (“XC1”), deep-dish wheel spacers and aerodynamically improved wing mirrors.

It was properly maintained by Porsche service centers and specialist workshops and had only one owner. It is powered by a 5.0L V8 engine with 326 hp (243 kW) compared to the 928 S4 which had 315 hp (235 kW) and 317 lb-ft (430 Nm) of torque. Power is sent to the rear wheels via a manual gearbox.

In 2003, the original odometer unit was replaced with a new one showing 56,636 kilometers. Documentation on file verifies that at the time of replacement, the original unit had recorded no more than 11,500 kilometers.

The auction will take place in Paris on January 31, 2024 and the estimated value of the car is between €180,000 – €280,000 EUR.
