Just looking at some vw pics on the interweb in my spare time got me thinking...

what sorts of styles make those vw categories? i see / hear people talking about "cal" or "euro" or "rat" etc. what types of body's, wheels or mods actually go in to making a car conform to one of those styles?

I suppose the rat category is basically a car which is a bit rusty and unmatched panels and that sort of thing, but what about the others?
