The world's most expensive two-door, four-seat convertible is a less formal interpretation of the classic Rolls-Royce design. From a technical perspective, this car combines a lightweight, extremely stiff aluminium spaceframe with the lean and elegant body of a drophead coupé. Hand-built to specific customer requirements from the finest materials, it includes a number of unique details. The rear deck is made from teak, using the same structure as that used in the yacht-building world, and the bonnet and windscreen surround are available in brushed stainless steel to give a contrasting, two-tone look. The use of steel and wood, cement the maritime theme.
