An exceptional and highly unusual example: a one-off right-hand-drive automatic prototype 550 Maranello, built by the Ferrari factory and Pininfarina as a special order—the only car of its kind in the world. Presented in Rosso Corsa over full Nero leather, with genuinely low mileage from a life spent in significant private collections. Key information • Unique one-off right-hand-drive automatic prototype, built by Ferrari and Pininfarina • Automatic gearbox with Tiptronic-style manual override, developed with Porsche • Originally a special order for the Brunei Royal Family's collection • Finished in Rosso Corsa 322 over full Nero (black) leather • 5,600 recorded miles • Recently serviced at a Ferrari main dealer, including cambelts and fuel pumps • Comes with book pack, tool kit, car covers and the rare cigar-lighter-powered spot lamp • Provenance paperwork including Ferrari Owners' Club documentation Model overview Launched in 1996, the 550 Maranello marked Ferrari's return to a front-engined V12 flagship after two decades of mid-engined Testarossas and 512s. Named after the town where Ferrari is based, it paired a 5.5-litre naturally aspirated V12 producing around 485hp with genuinely usable, grand-touring manners—true 180mph performance without sacrificing everyday comfort. Almost all 550s were built with a traditional manual gearbox, making genuine factory automatic examples like this one exceptionally rare—a fitting choice for a car built to a Royal collection's specification rather than for the ordinary production line.
