If you want “to boldly go where no man has gone before," a Rolls-Royce is a great choice. This beautiful ivory 1988 Silver Spur Sedan belonged to Star Trek creator, Gene Roddenberry, and was used as his everyday car while he was creating and producing Star Trek: The Next Generation. The car is is laden with luxurious amenities such as burled walnut trim, Wilton wool carpets and Connolly leather interior. The Rolls-Royce has a 124.5-inch wheelbase and is powered by an overhead valve 412-cid V-8 engine that produces 220 horsepower and is equipped with Bosch K-Jetronic fuel injection. Additional features are rear wheel drive, three-speed automatic transmission, rack and pinion steering, front wishbone suspension, independent rear suspension, front and rear disc brakes, and a steel body. Vehicle identification number, SCAZN02A0JCX22123. The Silver Spur model is the long-wheelbase version of the Silver Spirit. It was introduced by Rolls-Royce to the U.S. market in 1985 as a limousine, the first in 18 years. The initial MSRP was $185,000. The Saloon body style of the Silver Spur has the long wheelbase but not the dividing window, offering passengers plenty of interior space while driving toward any frontier.
The current owner will contribute 100% of the proceeds from the auction to the Roddenberry Foundation, an organization that supports and inspires efforts that create and expand new frontiers for the benefit of humanity. The foundation funds innovative solutions to critical global issues in the areas of science and technology, the environment, education and humanitarian advances.
