The Phantom is the first Rolls-Royce motorcar to be introduced since the company was acquired by BMW in 1998. Each Phantom is a unique combination of state-of-the-art technology and old-world craftsmanship, constructed with meticulous attention to detail. Manufacture of the Phantom begins in Unterhallerau, Germany, where its strong, stiff and lightweight space frame chassis is built. Each space frame and body shell assembly is then sent to BMWs factory in Dingolfing, Germany for corrosion-resistance treatment and primer paint. Next, each Phantom is shipped to a manufacturing facility constructed by BMW specifically to build the new generation of Rolls-Royce motorcars. It takes an average of 450 hours and the skills of hundreds of dedicated craftspeople, artisans, designers, engineers, mechanics, painters, sewing machinists and others to hand-build each car. At a base price of $380,000, the Phantom comes equipped with an impressive list of standard amenities including 90 square yards (75 sq meters) of A-grade Bavarian leather upholstery and book matched interior wood trim, hand-crafted from exotic veneers, all of which are fashioned right in the main assembly building of the Goodwood plant. With the Rolls-Royce customization, or bespoke program, however, the options are limited only by the boundaries of the buyers bankroll and imagination.
