Rolls-Royce ventured into new territory with the launch of the Ghost sedan in 2010. Smaller than the behemoth Phantom, the Ghost has proven to be the company's top seller, beating out the record set by the Silver Shadow II, which sold 3347 units in 1978. But don't expect that to be the end of it. According to reports, the Goodwood-based automaker is planning several offshoots on the Ghost platform in the coming years, aimed at helping it reach sales volumes of 4,000 units per annum.
