Never to be outdone by vulgar boutique hypercar marques or those pesky Italians, Rolls-Royce comes along occasionally to remind us of what is truly opulent, and what is truly expensive. Following in the footsteps of the Sweptail and the Boat Tail, is the Droptail, a new two-seater coach build of which just four will be produced, with each rumoured to cost over £20million. The first that we see here, revealed during Monterey Car Week, is called La Rose Noire.
