A stunning expression of Porsche’s technical excellence and the marque’s unwavering commitment to racing domination, the 959 pushed the limits of design, engineering and technology, and continues to amaze all who experience it, some 40 years after it entered production. Based upon a highly modified galvanized bodyshell derived from that of the 930 Turbo, the 959 was radically modified and updated. Pushing the limits of design, engineering, and materials science, the 959 featured lightweight bodywork including aluminum, polyurethane and the first automotive production use of extremely strong, yet light DuPont Kevlar.
Extensive wind-tunnel testing applied to the 959 yielded zero lift, high downforce, and optimal intake and cooling airflow. Underpinnings featured three ride-height positions, three shock-dampening settings, microprocessor-controlled ABS brakes with ventilated and cross-drilled discs, and new “run-flat” tires. The 959’s 2849cc flat-6 featured water-cooled cylinder heads, twin sequential turbochargers, and intercooling to deliver a stunning 450 brake-horsepower rating. Power was transmitted through an electronically-controlled all-wheel-drive system. Top speed nudged 200 MPH, with blinding acceleration, tenacious handling and anchor-like braking to match.
According to Excellence magazine, 339 examples of the 959 were built, including 16 prototypes, 21 “Vorseries” pre-production cars, 255 “Komfort” street models, 37 Sport models, and a final run of eight built in 1992 from remaining parts stores. Even at some $300,000 new, the per-car cost to manufacture was double, rendering the 959 “Porsche’s gift to its favorite customers.” Unrestored and offered with the odometer reading 3,521 miles at the time of writing, this 959 Komfort model is equipped with power windows, heated and power-adjustable sport seats, and an alarm system. Riding on special lightweight 17-inch magnesium wheels, this iconic and rare 959 represents, quite likely, the ultimate modern classic Porsche model.

First shown at Paris in late 1974, Porsche’s new 930 Turbo took the sports car world by storm with its technical excellence, electrifying performance and unique, totally involving driving experience. Released for sale in the spring of 1975 with highly anticipated U.S. exports commencing in 1976, Porsche’s 911-based 930 Turbo was the road-going expression of the many technologies gained from the all-conquering 917/30, which gained infamy as “the car that killed Can-Am” during the early 1970s.
Most importantly, the 930 Turbo represented the future direction of Porsche’s racing program. In particular, the aggressive, competition-only 935 der-ivation took overall victory at the 1979 24 Hours of Le Mans, as well as other major international endurance races, including Sebring, Daytona and the Nürburgring 1,000 km. Confirming the soundness of Porsche’s turbocharged racers, the “Slantnose” 935 won 123 of 370 races entered. Predictably, Porsche’s loyal and discriminating road-car clients demanded a “Flachbau” or “Slantnose” option for their 930 Turbo.
Offered with the odometer reading 57,432 miles at the time of writing, this later-production 1988 Porsche 930 Turbo Cabriolet sports 935-style factory “M505” Flachbau (Slantnose) frontal bodywork.

Stopping power is provided by 4-wheel cross-drilled and ventilated disc brakes residing behind staggered 16-inch Fuchs wheels.

Offered with its Porsche Certificate of Authenticity, owner’s manual, and service records, all organized within an attractive storage case, this factory M505 Flachbau 1988 Porsche 930 Turbo Cabriolet is ready to deliver a thrilling experience—with the top up or down.
