Porsche recently revived the legendary 935 Le Mans racer in a limited run of 77 examples. Based on the GT2 RS, the reborn 935 features copious amounts of carbon fiber composite parts and a twin-turbo 3.8-liter flat-six engine that produces 690 hp mated to a seven-speed PDK transmission. There is a catch, though – you can only tame this beast on the race track unless someone eventually converts it for use on the road. If, however, you really want to own a street-legal Porsche 935 right now, there's an original 1979 example currently for sale via Cartique by Mechatronik.

What you're looking at is an extremely rare one-off 935 built by Germany's Kremer Racing for the legendary F1 driver Walter Wolf that can be legally driven on the road. It's literally a race car for the road and is said to be 98 percent identical to the 935 K3 car that won Le Mans in 1979.

It's powered by the original race car's 2.85-liter, twin-turbo six-cylinder boxer engine, which has been slightly detuned to send 740 hp at 8,000 rpm to the wheels through a four-speed gearbox that still has the same gear ratios as the car that raced to victory at Le Mans. The bodywork is made entirely out of Kevlar panels and the car rides on original BBS race wheels wrapped in hand-built Goodyear tires.

Walter Wolf had an extensive list of special requirements for the one-off Porsche 935 road car. The speedometer had to be in kilometers and display the full range of the Le Mans gear ratio, which meant Kremer had to invent a special magnetic sensor for the rear axle.

The development of the new exhaust system also took nearly six months, while the suspension was modified with special Bilstein dampers and the race chassis clearance was raised up to four inches (instead of the original two inches) because Walter Wolf wanted to take the car on a high-speed grand tour around Europe.

Inside the luxurious interior, Kremer used Recaro seats and parts from the 930 Turbo. The seats are finished in dark blue leather with red piping. One of Walter Wolf's requests was refused, however. The racing driver wanted to have a second air conditioner in the passenger's side of the cabin, but was told it wouldn't technically be possible and "it would be better to wear just a polo shirt while driving in the summer months."

Pricing is only available on request, but to give you an idea of the car's original value, Wolf paid 375,000 Deutsch Marks for the car back in 1980, which was around $800,000 at the time.
