This Porsche collection gives the Hamptons White Party a run for its money.

In early December, RM Sotheby’s will auction off a mysterious trove of nearly 60 white sports cars from the German marque. Titled the White Collection, the monochrome rides were compiled over a decade and feature some of the finest Porsches of all time, including six that could sell for seven-figure sums.

The identity of the collection’s owner may be unknown—along with their exact location—but one thing’s for sure: They love a white hue. There are a couple of exceptions, but nearly all the 56 cars set to hit the block were factory-issued in unique shades of the color. If that wasn’t enough, the building where the vehicles are stored has white walls and is filled entirely with white furniture.

The highlight of the collection is an entirely unique example of the company’s modern-day hypercar, the 2015 918 Spyder. Outfitted with the weight-saving Weissach package, the 875 hp speed machine is finished in paint-to-sample Grand Prix White. It’s expected to fetch between US$2.5 million (HK$19.58 million) to US$3 million (HK$23.49 million).

There are plenty of 911s to choose from, too. Chief among these is a 1993 911 Carrera RSR 3.8 also finished in Grand Prix White over a stunning red-and-white leather interior. It’s likely to sell for between US$2 million (HK$15.66 million) and US$2.5 million (HK$19.58 million). Other 911s of note include a hand-built, air-cooled 1997 911 GT2 (expected to sell for between US$2 million (HK$15.66 million) and US$2.2 million/HK$17.23 million)) and a barely driven 1994 911 Turbo S X85 ‘Flat-Nose’ (US$1.5 million/HK$11.75 million to US$2 million/HK$15.66 million). There’s also a 1973 911 Carrera 2.7 Lightweight with red graphics and wheels and a 1973 911 Carrera 2.7 Touring with blue graphics and wheels (US$900,000/HK$7.05 million to US$1.2 million/HK$9.40 million). If none of those catch your eye, there are two red Porsche tractors, along with over 500 museum-grade accessories, parts, tools, and literature.

The White Collection is set to be auctioned off over two days in Houston, Texas, on Friday, December 1, and Saturday, December 2. Whether you’re in the market for something special or something unusual, there should be a car for every type of Porsche collector.
