2010 Porsche 911 GT2 RS

Believed to be one of just 24 UK-supplied cars from a global run of 500, this 2010 Porsche 997 GT2 RS is the model that took the Mezger-derived 3.6-litre twin-turbo flat-six to its peak: 612 bhp to the rear wheels only, through a six-speed manual with no electronic safety net. Carbon fibre, polycarbonate rear glazing and a single-mass flywheel bring the weight down to around 1,370kg, and it remains the most powerful manual-gearbox production Porsche ever sold. This example has covered just 4,856 miles.

The specification is what sets it apart from the usual GT2 RS. Finished in Black with a black leather interior, it was ordered in rare Comfort form, with the Club Sport Package deleted and Adaptive Sports Seats fitted from new. That gives it a more understated, road-focused character than the typically stripped-out car. Other notable options include 19-inch centre-lock GT2 RS wheels, carbon front fenders, Porsche Ceramic Composite Brakes, PCM 3.0 with extended navigation, Sound Package Plus and a contrast White Gold Metallic accent.

The car now wears Porsche carbon fibre bucket seats, but the original Adaptive Sports Seats are included in the sale. A new owner can keep the current, more focused setup or return the car to its factory configuration. It comes with a Romans International Platinum Warranty.
