He bought his way into Formula 1 racing and very nearly paid for it with his life. Given up for dead after an appalling accident he recovered by what the medical profession called sheer force of will. His astonishingly quick return to the cockpit was called the most courageous comeback in sporting history. After winning two championships he got bored and left the sport, only to return again and win another. During his remarkable career he was called both a hero and a villain. The battle-scarred champion who defied both the odds and convention remains a sporting legend.
