About this car
This 1987 Porsche 911 Turbo Flachbau Cabriolet stands out with its factory M505 Slant Nose conversion, delivered through Porsche's exclusive Sonderwunsch program. Finished in Midnight Blue over a Sky Blue leather interior, the car pairs its dramatic low-profile nose and pop-up headlights with a power-operated convertible soft top for open-air driving. The turbocharged 3.3L flat-six engine sends power through a 4-speed manual transmission to the rear wheels, delivering the raw, analog character that defines air-cooled 930 Turbos of the era.
With 68,581 miles recorded, this example retains its period-correct presence and is supported by service records along with a clean CARFAX report. The two-door convertible body features power windows, air conditioning, and central locking, all contributing to a refined yet visceral grand touring experience. Every element reflects the outrageous performance and unmistakable styling that made the M505 Flachbau one of the most distinctive expressions of the 1980s 911 Turbo.

The Porsche 911 Carrera G-Series, produced between 1974 and 1989, represents a significant evolution of the iconic 911 lineup. Over its 15-year production run, approximately 196,000 units were manufactured across various trims, including the Carrera, making it one of the longest-running generations of the 911. The G-Series introduced key updates like impact bumpers to meet U.S. safety regulations and galvanized steel bodies for improved corrosion resistance, enhancing longevity—a critical factor for collectors.
Engine options varied, with the Carrera models typically featuring air-cooled flat-six engines ranging from 2.7 to 3.2 liters, producing between 175 and 231 horsepower depending on the year and market. Performance highlights include the 1984-1989 Carrera 3.2, which achieved 0-60 mph in around 5.6 seconds. Notable for collectors are rare variants like the 911 Turbo (930) and special editions such as the 1988 Commemorative Edition, built to celebrate 250,000 911s produced. Values have risen steadily, with well-maintained examples often fetching over $50,000, and rare models exceeding $100,000 at auctions. The G-Series’ blend of classic design, durability, and historical importance as a transitional model makes it highly sought after in the exotic car market.
