There are special Porsche 911sand then there are cars like this.
This spectacular 1989 Porsche 911 Turbo Cabriolet was factory-equipped with Porsche's legendary M505 Slant nose (Flachbau) package, transforming the already formidable 930 Turbo into one of the most distinctive and sought-after Porsches of its era.

Inspired by Porsche's dominant 935 race cars, the factory Slant nose 505 were genuine factory-built Porsche Slant nose models.
Finished in stunning PTS Velvet Red Metallic over a red leather interior with a matching red convertible top (as per the build sheet), this 930 delivers quintessential late-1980s Porsche presence.

Power comes from Porsche's legendary turbocharged 3.3-liter air-cooled flat-six, paired with one of the most important features of the 1989 model: the G50 5-speed manual transaxle. The final-year 1989 930 was the first and only model year of the original 930 Turbo to receive the 5-speed gearbox.
The car is additionally equipped with a limited-slip differential, creating an outstanding combination of turbocharged air-cooled performance and the improved drivability of the G50 transmission.
