About this car
The 1989 Porsche 911 Turbo Cabriolet stands out for its factory M505 Slant nose conversion on the final-year 930 chassis. Finished in Velvet Red Metallic over red leather, the car carries a red power convertible top and rides on 16-inch forged Fuchs alloy wheels.
Power comes from the turbocharged 3.3-liter air-cooled flat-six paired with the G50 five-speed manual transaxle and limited-slip differential. The M505 package adds signature slant-nose front fenders, vented front fenders, rear-quarter cooling intakes, front and rear spoilers, and factory retractable headlights. Four-wheel ventilated disc brakes handle stopping duties.
Inside, heated and power-adjustable front sport seats sit before a Blaupunkt cassette stereo, with power windows completing the cabin equipment. The example shows 70,247 miles.

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.
