The 1988 Porsche 911 Turbo Cabriolet M505 comes from the era that earned the 930 its legendary Widowmaker reputation. Known for its raw turbocharged power and rear-engine excitement, these Turbos reward skilled drivers with a thrilling and unforgettable driving experience.
This example features the factory Slant Nose M505 Flachbau package, instantly recognizable and dramatically different from a standard 930. Its rarity is remarkable, with only about 15 Slant Nose Cabriolets imported to the United States in 1988, making this one of the most collectible Turbos of its generation.
The 3.3-liter turbocharged flat-six is paired with a 4-speed manual transmission, delivering a connected and high-performance driving experience. A limited-slip differential keeps the car planted, while factory forged Fuchs alloy wheels complete the classic 930 look.
Finished in Grand Prix White, the paint shows its age with visible imperfections, reflecting a car that has been enjoyed over the years. The full blue leather interior and matching soft top remain complete, though well-worn with torn seat bolsters, a cracked dash, and frayed steering wheel stitching. The cabin offers a perfect starting point for a restoration or continued driver enjoyment.
Factory options include a power convertible top, alarm system, and lumbar support. An upgraded sound system features the factory amplifier with a modern Pioneer head unit. A binder of receipts documents decades of maintenance and service, providing a clear history for collectors.
This M505 Slant Nose 911 Turbo Cabriolet is an extraordinary opportunity for serious collectors. While it will require a full restoration to return to concours-quality condition and win shows again, it can also be enjoyed today as a driver-quality example that delivers the excitement and character of a true 930 Turbo. Its rarity, performance, and historical significance make it a standout addition to any collection.
