With most car's ranging in the six-figures, Rolls-Royce has built a reputation for excellence since their founding in 1906. Which makes the news that the British luxury-car manufacturer recently unveiled their most expensive vehicle all the more exciting. Adding to the drama is the fact that the Sweptail, as the car is being called, is a one-off vehicle that took four years to create by hand, and features a full-length panoramic roof that culminates in a tail-like rear of the vehicle. In total, the custom-built car costs a whooping $12.8 million.

The Sweptail is a two-seat coupe that was the dream of a longtime Rolls-Royce customer. In 2013, the undisclosed male owner commissioned the car company to build a vehicle that would take on many of the aesthetics of the swept-tail Rolls-Royces' of the 1920s and '30s. Much of the clients love for the vehicles of that era came from his current passion for yachting. As such, the designers and engineers came up with a bespoke car that included an ample of amount of wood interiors, as well as a long, uninterrupted glass roof to enjoy the sky, much like from the deck of a yacht. Just to make the interior that much more glamorous, the team at Rolls-Royce added a button that, when pushed, deploys a chilled bottle of the owners favorite champagne along with two crystal flutes.

The all-glass roof extends to the back in a design that pays homage to modern yachts as well as historic Rolls-Royce's from the early 20th century. James Lipman

The eight-figure car was unveiled over the weekend at the Concorso d’Eleganza at Villa d’Este in Italy. Rolls-Royce CEO Torsten Müller-Ötvös expressed his pride in designing the historic vehicle at the ceremony, “Sweptail is a truly magnificent car. It exudes the romance of travel for its own sake, and immediately places ‘Sweptail’ in the pantheon of the world’s great intercontinental tourers...We are listening carefully to our most special customers and assessing their interest in investing in similar, completely exclusive masterpieces."
