Goldfinger used a 1937 Rolls-Royce Phantom III Sedanca de Ville with coachwork made from actual gold to smuggle the metal from England to Switzerland, where the body of the car is melted down and voila—he avoided some kind of banking-schmanking regulation. Once the body of the car was melted down, the original coachwork went back on and he’d return to England to repeat the operation.
