Car 9 months ago Share Tweet Pin Share Last month saw the auction of Muhammad Ali‘s 1976 Alfa Romeo Spider, and this month, another model from the boxing legend’s automotive collection is up for grabs — his 1970 Rolls-Royce Silver Shadow Convertible. Muhammad Ali purchased this top-of-the-range model in December 1970 when he was still known as Cassius Clay, possibly in celebration of regaining his boxing license (and passport) for nearly five years after refusing to be drafted for the US military during the Vietnam War. One of the most expensive Rolls-Royces during its time, this Silver Shadow Convertible was first owned by Ali for six years until it was passed to a second owner in the US before finding its way to its current owner in Holland. The car has never been fully restored and still retains most of its original interior, however it has undergone a color change and significant mechanical improvements. In addition to standard documentation, the car also comes with a copy of Clay’s temporary drivers license and a photo book including a photograph of Ali and Diana Ross with the Rolls-Royce outside Caesar’s Palace. Muhammad Ali’s 1970 Rolls-Royce Silver Shadow Convertible is now up for auction at Bonhams. Take a look at the glamorous model above and also check out Rolls-Royce’s ultra-limited “Silver Ghost” collection. Bonus: Want to stay up to date on our latest Rare Norm news ?
