1993 Porsche 911 Carrera 3.8 RSR Is So Rare It'll Make Your Eyes Water

Auction house RM Sotheby's is tasked with finding new owners for the cars. Included in a batch that will forever be known as the White Collection, all 56 are expected to earn their owner a staggering $30 million.

The reveal of the impressive lot has gotten us all worked up, so we've decided we'll try to cover as many of the Porsches as possible until the hammer falls more than a month from now. On Thursday, for instance, we took a look at the most expensive car in the collection, the $3 million 2015 Porsche 918 Weissach Spyder.

Cheaper than that one by about half a million dollars is the 1993 Carrera 3.8 RSR now sitting before you. If all the stars align, it'll probably fetch as much as $2.5 million – a far cry from the car's original price of "just” $215,000.

The reason for the high sale price the owner is hoping for is the car's rarity. The Porsche is just a touch away from being unique, and so highly-specced that it'll most likely make you cry with desire.

Officially the 911 is a Strassenversion of the RSR, of which just two were made with a full leather interior. It is also the last of the 51 units Porsche Motorsport-built in this configuration.

The 964-generation Porsche may be titled a 1993 model year, but it was actually completed and delivered by the German carmaker three years later, in 1996. Coincidently, that's two years after the Germans officially stopped making the specific chassis it is built on.

And that is not because of some issues with the build process, but on account of the care and amount of unique fittings that went into the build.

We're told the car, wrapped in a shade of white called Grand Prix, spent the period from 1996 to 2015 hidden away from sight, for reasons that are lost to history. Eight years ago it was rediscovered, together with its sister car in Polaris Silver Metallic, and joined the White Collection.

The fact it was never used means the miles on it are very low, with the odometer indicating just 43 miles (70 km). It also means the Can Can Red leather interior is in tip-top shape, from the seats to the dashboard and from the control knobs to the door pins.

And that's not even the impressive part. Unlike most other Porsches of its kind, this one features the twin-ignition 3.8-liter engine the world has gotten to know as the Le Mans. The numbers-matching engine is tied to an equally native type G50 gearbox. The Porsche also comes with a 120-liter fuel cell, a locking rear differential, and an air jack system.

The Porsche rides on Speedline RS wheels painted in Amethyst Metallic, behind which gold brake calipers can be seen. The wheels are still wrapped in the original tires.

Although not raced, the 1993 Porsche 911 Carrera 3.8 RSR is part of a breed that was successfully campaigned in endurance races at the world's most famous tracks, including Suzuka, Interlagos, Sebring, and of course Le Mans.

The fact it was barely used may have some people worrying about the fact it may not work as it was supposed to, but RM Sotheby's says the car "has been started and run to operating temperature monthly."

Not all the parts now fitted on it are the original ones. The gas tank liner, for instance, was replaced with an OEM one for reasons that have not been disclosed. No other maintenance work seems to have been performed on it.

Unlike the 2015 Porsche 918 Weissach Spyder we discussed yesterday, this variety of Porsche does not come with a wealth of accompanying documents and other automobilia. The seller does throw in the fact the RSR is documented in the Porsche 964 Carrera RS 3.8 book published in 2017 by German racer Jürgen Barth.

Technically speaking RM Sotheby's estimates the car, described as "the wildest 964 ever ordered by a Porsche VIP," can fetch anywhere between $2 million and $2.5 million. We will of course keep an eye out for the final sale price and come back with an update as soon as we learn more.

Meanwhile make sure you check back with autoevolution daily as we continue to cover the incredible Porsche cars featured in the White Collection. Tomorrow, for instance, we'll be talking about a 1997 Porsche 911 GT2, one of just 17 to have been made for the Japanese market. And there's a huge price on that one as well.
