- Jaguar Racing, in collaboration with the film Ocean's Twelve, mounted a $250,000 diamond on the nosecones of its cars for the 2004 Monaco Grand Prix, aiming to garner attention through an unparalleled PR stunt. However, driver Christian Klien's first-lap crash led to the diamond's disappearance, sparking widespread speculation and intrigue.
- Nav Sidhu, Jaguar Racing's director of communications at the time, orchestrated the stunt to leverage Monaco's luxury setting and celebrity presence for promotional impact. Despite the risks, real diamonds were used to authenticate the stunt, emphasizing the high stakes involved.
