Among the finely curated vignettes of Porsche models at the White Collection is a selection of wildly specified late-model 911s. These are the embodied results of a challenge put forth to Porsche’s Exclusive Manufaktur department: Can you build it like this?

With a staggering as-delivered MSRP of $639,345, amounting to an outrageous 217% premium over the base price of a standard 2019 GT2 RS, this strictly one-off vehicle from the White Collection is the perfect representation of this curatorial theme.

The White Collection’s stunning 2019 GT2 RS—to date, the most powerful 911 production car thanks to its 690-horsepower (700 PS) twin-turbocharged 3.8-liter flat-six—is presented in paint-to-sample Grand Prix White (9A5), which conspicuously extends to a host of non-standard areas including the front and rear aprons, SDARS antenna housing, and side skirts. Even the plastic mesh inserts in the rear decklid and front bumpers have been clad to match.

Notably, this car was selected with the ultra-desirable Weissach performance package; however, all the requisite carbon fiber trim and lightweight components have been finished (per the consignor’s demand) with a beautiful dark blue tint. The car’s roof is a brilliant, contoured panel of exposed blue carbon fiber, and this visual appeal bleeds gracefully into a pair of matching blue carbon stripes, blue carbon side mirrors, and massive blue carbon rear wing.

Moreover, the car’s exterior features the stylish light design package, extremely practical front-axle lift system, PDLS headlights, and clear taillights. This GT2’s last, emphatic, visual coup de grace is the staggered set of magnesium Weissach wheels custom-rendered in Dark Sea Blue paint.

The dazzling carnival of visual delight continues—with grand emphasis—into the car’s passenger cabin, which includes nearly every available option and creature comfort. Stepping across the illuminated carbon-fiber door sills, one is greeted by acres upon acres of sumptuous, finely tailored Yachting Blue leather upholstery trimmed with Pebble Grey stitching and Bianco Leda piping throughout. Every interior surface has been custom-specified (CXX) in Yatching Blue leather, and not even the smallest piece of ornamentation seems to have escaped the consignor’s especially fine attention to detail.

Beneath the special Yachting Blue Alcantara headliner, the dashboard is finished in Yachting Blue leather trim, with the steering column, steering wheel, center console, and more than 25 additional areas adorned-to-match. The gauge suite and Sport Chrono package clock all wear matching paint-to-sample Grand Prix White faces, while a smattering of blue carbon fiber elements (and Yachting Blue carbon fiber floormats) ensures absolute continuity with the car’s exterior appearance. Though driven fewer than 15 miles from new, this car has been started and run to operating temperature monthly.

The White Collection’s custom-tailored 911 GT2 RS “Weissach” would be an absolutely spectacular acquisition for any Porsche collector looking for a pristine, over-the-top example of the world-class capabilities of the marque’s Exclusive Manufaktur department—to say nothing of the model’s undeniable, purebred performance.
