As Brian pointed out a Swiss S2 Fulvia saloon in the Brinks Mat BBC drama (shame about the wheels?) Following on, the BBC came up with a documentary: The Gold: The Inside Story. Original film taken outside the Heathrow warehouses where the Police were stopping all vehicles. Parked up was a Beta saloon. Maybe some gold in it? After all, getting 3 tonnes of gold (6,840 bars) into a Ford Transit and driving it away would be a challenge.
