Definitely an Austin Cambridge, it was left hand drive too. There was another car that falls off the transporter though, and that was a Lancia. A 1950's Lancia Appia, a rare car nowadays as there weren't that many built in the first place......God I must get out more
It's one of those films that is great for spotting though.
The Aston pushed off the cliff is a disguised Lancia apparently. It's certainly not the Aston cos when it goes down the cliff the bonnet opens the opposite way as it did when Charlie Croker was fiddling with it in the parking garage.
Also as the Mini Coopers get pushed out the bus they only have one petrol cap as opposed to two.
