One client, one coupé
Sweptail is the single commission that reopened coachbuilding at Goodwood. Its collector case is the complete object: one chassis, a four-year factory programme and a body that was not offered to anyone else.

Overview
A Rolls-Royce client approached the company in 2013 with a request for a two-seat coupé informed by pre-war coachbuilt Rolls-Royces, racing yachts and the client's own aircraft and yacht collection. Giles Taylor's design team developed the car with him over four years.
The references were specific: the Jonckheere Round Door Phantom I, Park Ward's streamlined Phantom II and two swept-tail bodies from Gurney Nutting and Park Ward. The result kept Phantom VII Coupé running gear but replaced the production body and cabin with a single-client design.
Rolls-Royce revealed Sweptail at Villa d'Este in May 2017. No attributable public resale has followed, and the factory never disclosed the commission price.

HICON BID
A HICON Bid is a confidential expression of buying interest on the Rolls-Royce Sweptail file — never public, never shown to other members. It is not a binding purchase, and HICONIUM holds no funds.

The vault
You keep one? The record starts in your garage — identity, papers, photography, and the market evidence this file already carries, bound to your chassis.
The value drivers
Two F40s can be indistinguishable in a photograph and a million apart at the hammer: the difference is never in the paint. Build the file below and watch the band move.

Spans are indicative, drawn from the documented sales cited beside each attribute. The calibrated multipliers — and how they compound for one specific chassis — are member instruments.
The hands
The people whose work shaped the Rolls-Royce Sweptail.
Director of Design
Led the design department through the four-year Sweptail commission and described the work as tailoring a car to one client rather than adapting a series model.
