Some of Rolls-Royce’s most valued customers are about to get access to a new level of opulence.

The British marque has just announced the Coachbuild Collection, a series of ultra-exclusive, “super-luxury” production cars never to be repeated. The program will be invite-only, offered only to Private Office customers with a “deep affinity” for the brand and its design capabilities.

No automaker does bespoke like Rolls-Royce, but Coachbuild Collection is meant to be so much more. In a throwback to its earliest days—and in response to an increased demand for higher levels of exclusivity—the company plans to offer clients strictly limited builds that feature wholly unique bodies on top of a preexisting automotive platform. These vehicles will be more in line with dazzling cars like the Boat Tail and Droptail (seen above), as opposed to a highly customized Ghost.

Rolls-Royce has a knack for building automotive works of art, but the Coachbuilt Collection are meant to be taken out on the road, not parked and put on display. Rolls-Royce says each vehicle will be “created to be driven,” and is fully homologated and street-legal throughout the world.

Coachbuild Collection won’t just end up with a personalized vehicle, though. The automaker stressed that the new program is a “multi-year journey of unforgettable experiences.” Clients will be granted access to the company’s closed testing facilities and get to witness the vehicle’s development firsthand. They’ll also be able to play even more of a role in the design process and be welcomed into the ateliers of the master craftspeople who will hand build their vehicles.

“The experience of this program is inseparable from the motor car itself, and both will be brought to life with the care and ambition worthy of the collectors who inspired them—and of Rolls-Royce itself,” Chris Brownridge, the marque’s chief executive, said in a statement.

Rolls-Royce also announced that each Coachbuilt Collection will have its own singular vision. As such, it’s interesting that the basis for the debut release will be the company’s first electric vehicle, the Spectre. That all we know about the car right now, but luckily we won’t have to wait much longer to find out more, with more details promised to be revealed next month.
