In 1997, an Aston Martin DB5 that originally appeared in Bond film Goldfinger was stolen.
Nobody knows how it was taken - though plenty have speculated it was dragged by its axles from the Florida airport hanger in which it was being stored and loaded onto a waiting cargo plane - and it hasn’t been seen since. Very 007. Investigations by authorities, insurance companies and so on have turned up little. Current thinking is it’s somewhere in the Middle East, but some maintain it’s lost forever at the bottom of the sea.
