The Ruf CTR is the high-water mark for air-cooled Porsche 911s.
The CTR (that's Group C, Turbo, Ruf) gave hidings to the '80s most indulgent supercars, and built Ruf's reputation as a legendary tuning house.
The Nurburgring-Nordschleife carving 'Yellowbird' Ruf CTR captured the heart of the motoring media in 1987. It earned 'Road&Track' magazine's highest honour, named 'Fastest production car in the world'.

Every possible detail of the CTR was agonized over, built by Ruf from bare chassis up. Every panel was replaced with a lightweight alternative, the chassis was seam welded with rain gutters removed for better aero performance.
Custom brakes, suspension and a bespoke five-speed gearbox controlled the pace of the manic 3.4-litre twin-turbo flat six fettled with race parts, including the fuel injection system from Porsche 962 race prototypes.
Test driver Stefan Roser's 'Faszination on the Nürburgring' showcased the CTRs visceral ability. The video is a staple in the automotive enthusiast diet.
Renowned for balance, the CTR made drifting a 911 a less volatile endeavor. High-speed tests at the Nardo Ring saw the CTR reach 342km/h, showing it's whale tail to a trio of icons; Porsche's 959, the Ferrari F40 and the AMG Hammer.
Ruf produced just 29 CTRs and it is understood up to 30 were built as conversions for customers who provided their car.
And now you can buy one. And it's black.

Assuming the car is the same as the one sold just two years ago by Sotheby's in Monaco, it was built from the factory as a 930 before undergoing Ruf's 'BTR' conversion.
The owner enjoyed the BTR for three years until heading back to Ruf for the full CTR conversion in 1992, including an updated six-speed box.
The three-owner CTR retains options like a stealthy GPS, adjustable heated seats and an electric sunroof, forgoing the roll cage for a more demure appearance. The car appears to have been specced for blitzing the autobahn rather than hitting ripple strips and the immaculate body suggests little track activity.

You can pre-order a new Porsche GT2RS for just under $650k, but if you want to create a titter when you pull up to the café, similar CTR models have been listed for around A$500,000 (911s have gone north since the car saw Sothebys).
A regular black Porsche 930 Turbo might earn Instagram likes from Magnus Walker. A Ruf CTR will have him offering to shave his dreadlocks off for a whip around the block.
