There is a large USA vehicle featured in this film. The closest I can come to identifying it is as a [b]1959 Pontiac Parisienne Convertible[/b]. However there are some minor differences between the car on the film and the only set of photos that I have found on the web.

Some of the differences can be attributed to modifications by owners of the vehicle, whilst others are design features e.g. shape of external mirrors.

Anyone have a better idea of what this vehicle is? Unfortunately I only saw the film on TV and have no screen captures of the vehicle.
