A dream car for many since it first hit the road in 1975, Porsche’s first-generation 911 Turbo, known internally as the 930, quickly established itself a global performance benchmark. With huge flared fenders and a whale-tail rear deck spoiler, it certainly looked the part as well, all while being instantly recognizable as both a Porsche and a 911.

In 1982, Porsche racing sponsors requested that the German automaker’s Exclusiv Manufaktur—sometimes called Sonderwunsch, or “Special Wishes”—program create a unique road car that looked like the world-beating type 935 racer. The resulting bodywork indeed bore a close resemblance to the aerodynamic 935, with louvered steel front fenders made flush with the hood and fitted with retractable headlamps. The rocker panels were boxed and extended to meet the widened rear quarter panels, which contained new brake-cooling vents with side strakes and an electric fan for additional oil cooling. Wider wheels and tires were fitted at both ends.

Within months, Porsche was overcome with customer requests for the 935-inspired Flachbau, or “Flat-Nose,” treatment. Unsurprisingly, these cars were typically optioned by only the wealthiest clientele, and with many additional factory upgrades. During the 1988 model year, Porsche completed just 148 coupe examples for the North American market.

On offer is one such example. Completed in December 1987, this 911 Turbo was originally delivered to an individual in Atlanta, Georgia. Finished in the classic shade of Guards Red over a Black leather interior, this Flat-Nose, like many of its siblings, left the factory with a desirable list of options. Leather swathes the bulk of the interior, extending to the steering wheel, heater console, stalks, brake lever, and seat belt latch. In addition to the highly exclusive M505 Flat-Nose special option, the build sheet further includes a limited-slip differential, an electric sunroof, a black velour luggage compartment, an alarm system, and a Blaupunkt Reno stereo. Now presenting with just 7,531 miles on the odometer at the time of cataloguing, the desirability of this Porsche is enhanced by its numbers-matching engine and transmission.

A unique and particularly rare example of the 911 Turbo, this M505 equipped Flat-Nose example’s desirability is further bolstered by its limited mileage and luxurious appointments. With just 148 such cars built for the North American market in 1988 model year, this Porsche will surely be coveted for decades to come.
