About this car

This 1989 Porsche 911 Turbo Cabriolet is one of just 48 cars with the G50 five-speed gearbox supplied new to the UK that year. The 3.3-litre turbocharged flat-six produces 300 bhp, and the car is finished in Guards Red over cream leather with red piping and red carpets.

Specification includes front seat heating, climate control, a 40% locking differential and a graduated tint windscreen. The car has been with the same keeper since 1998.

It shows about 65,000 miles. The service history is unusually complete, with an entry almost every year from 1991 to October 2025, first at Lancaster Porsche and AFN, then at Parr Porsche. Annual mileage has been very low in recent years.

Porsche 911 buying guide

The Porsche 911 has been in production since 1964 and has kept the same basic layout throughout: a flat-six engine mounted behind the rear axle, two seats up front and two small ones behind. The range runs from the everyday Carrera and Targa to the four-wheel-drive Turbo and the track-focused GT3 and GT3 RS. Buyers choose it because it works as a daily car, is well built and has a large network of independent specialists.
