About this car

This 964 Carrera 4 Cabriolet is a one-off, built about ten years ago by the dealer's own Special Requests department as an alternative to a modern 911. Its air-cooled 3.6-litre flat-six has a TPC Racing supercharger and intercooler, which the page says lifts output to over 350 bhp and 450 Nm. The car keeps its five-speed manual gearbox.

The chassis changes are 993 front brake calipers, adjustable Bilstein suspension, H&R springs and 18-inch Fuchs-style alloys. The bodywork has slightly wider arches, a rollover bar, a 993 hood, 993 door handles and teardrop mirrors, with the side repeaters deleted. It is painted in Gulf-inspired blue and orange. Inside are Nightblue Nappa leather with orange stitching, Gulf blue dials and a Blaupunkt Bremen head unit with Focal speakers.

The odometer shows 17,374 miles since the build. The dealer holds the invoices and receipts from its creation.

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.
