The Rolls Royce Phantom Drophead Coupe is among the richest and rarest vehicles in the world. Only 80 will make it to the U.S. market in any given year and it will take 18 months before the owner gets his new car. The 2-door, 4-seat convertible is hand-built with a rigid and lightweight all-aluminum spaceframe chassis mated to a sleek, streamlined convertible body. Power is provided by a 6.75-liter V-12 engine that produces 0 to 60 mph acceleration in 5.7 seconds.
