Have you ever noticed in TV programmes like Poirot - where vintage cars/buses/lorries have been procured - they're always spotlessly clean - as if! No matter what the weather, no matter what the road conditions are. And never a dent or a speck of rust.

It's always interesting to recognise a location which is actually miles away from the spot in which the drama is supposed to be set. 'Foyle's War' - which I love to death - actually uses only a very few real locations in its Hastings setting. Foyle's house is one of them, but not much else.
