The people behind the car
The people whose work shaped the Rolls-Royce Corniche.

The four-seat coastal tourer
The Corniche turned the Silver Shadow's two-door body into a 24-year model line. Convertibles define demand; late Corniche IV cars sit above early examples. The 25 turbocharged Corniche S cars stand apart.

Estimate band for good road cars. 33 documented sales since 2019 plotted below.
Band and axis shown in USD. Sale positions use indicative fixed-rate conversion to USD; sale readouts retain recorded currencies. USD; documented, serviceable coupés and convertibles. Corniche S and exceptional low-mile cars require separate comparison.
Instrument calibration for this file is in progress — the terminal above reads the documented record directly.
Amounts are reported auction results including buyer's premium. Roof operation, hydraulics, cooling, wood, leather and corrosion require inspection.
Overview
The two-door SY body began as a Silver Shadow derivative at Mulliner Park Ward. Rolls-Royce applied the Corniche name in 1971, keeping the 6.75-litre V8, automatic transmission, independent suspension and high-pressure hydraulic systems.
The fixed-head car left production in 1981. The convertible continued: Corniche II arrived in 1986, Corniche III in 1989 and Corniche IV in 1992, when production moved from Mulliner Park Ward in London to Crewe.
BMW Group Classic records 5'146 Rolls-Royce Corniche convertibles through 1995. RM Sotheby's cites 1'108 coupés. Published grand totals differ slightly, so body-style and series figures should be stated with their source rather than collapsed into one exact number.
