The £3 Million 911 You've Never Heard Of

If you attended Secret Meet and wandered into RM Sotheby’s star-studded garage, once you’d finished drooling over the black F50, you might have wondered why someone didn’t wash the silver Porsche 964 RS in the corner.

Well, that wasn’t a 964 RS at all. It was a 911 you’ve likely never heard of — one of just two Carrera RSR 3.8 Strassenversions ever built.

The Carrera RSR 3.8 was built from Porsche's successful Carrera Cup race car and developed as the company's return to GT racing following the collapse of Group C. It was a lightweight, stripped-out competition machine powered by an air-cooled 3.8-litre flat-six producing up to 380hp.

Only 51 RSRs were built by Porsche Motorsport, and they quickly became one of the dominant GT racers of their era, taking victories at the 24 Hours of Spa, 1000 Kilometres of Suzuka, and 24 Hours of Interlagos, as well as a class win at Le Mans, the top four places in category at Daytona, and a class win at Sebring.

But two cars were different.

During the mid-1990s, one particularly important Porsche customer placed an extraordinary order with Porsche Exclusive Manufaktur. All six cars were completely individual, but shared purple wheel centres and gold brake calipers. The order included multiple Turbo S Lightweights and, crucially, two road-going Carrera RSR 3.8 "Strassenversion" models. These weren't simply race cars fitted with number plates. They were bespoke creations built to a standard Porsche had never offered before and never has since.

One of those cars was chassis 496107. Finished in Polar Silver Metallic, it featured an interior unlike anything else to leave Stuttgart at the time. Guards Red leather covered almost every visible surface, including the dashboard, steering column, centre console and even the roll cage itself. The carpets, harnesses and headlining were all colour matched, while details such as the switches and stalks received leather trimming of their own.

Underneath, however, it remained every bit the racing car. The car retained the uprated twin-ignition Le Mans-spec engine, a full air-jack system, a 120-litre fuel cell and a motorsport differential.

And then came the strangest part of the story. Rather than being driven, enjoyed or campaigned on track, both cars disappeared into storage for almost 20 years. When chassis 496107 resurfaced in 2015, it still wore its factory-applied protective Cosmoline coating and showed just 10 kilometres on the odometer.

Today, it remains one of the most remarkable air-cooled Porsches ever built. One of just two road-going RSR Strassenversion models, it is arguably rarer and more significant than many of Porsche's better-known halo cars.
