For sale: Unused Porsche 911 Carrera RSR 3.8

PORSCHE fanatics, it’s time to sell everything you own. One of the rarest and most collectable air-cooled 911s is going to auction next month with just 10km on the clock.

This Porsche 911 (964) Carrera RSR 3.8 was special ordered new in 1993 and is one of 51 ever made, and one of just two to be fitted with a fully trimmed interior.

Weissach built the RSRs for the track and most sold to race teams. This one, however, has never seen a circuit in its life. It has instead languished in a private collection in completely original and virtually untouched condition, still covered in a rust-preventative coating called Cosmoline as fitted by the factory prior to delivery.

“Specified with Polar Silver Metallic paint and trimmed in Can Can Red leather, including the competition seats (whose rear panels were painted body colour), headliner, upper and lower dashboard, steering column and steering wheel, door caps, and even the bolt-in roll cage,” says the RM Sotheby’s auction house listing.

“The centres of the wide Speedline three-piece wheels were ordered in Amethyst Metallic, while the callipers for the huge disc brakes are painted a contrasting gold.”

Sitting in its rump is a race-ready, dry-sumped, naturally aspirated flat six with outputs conservatively listed at 260kW and 360Nm. The truth is considered to be somewhat higher than that.

It’s the same engine as was found in the more common Carrera RS 3.8, though that car missed out on the wider, turbo body of this competition-bred RSR.

How any Porsche obsessive could allow a car like this to sit dormant for 24 years is hard to imagine, but it has the potential to set auction records when it goes under the hammer on May 27.

Other 964 RSRs sold in recent times have neared the A$1m mark, but none have been quite as unique as this one.

Examples of these RSRs that did make it to starting grids won races all over the world, including 24 hour enduros at Spa, Daytona and Interlagos, and the Suzuka 1000km.
