Sorry if this is a daft question, but how interchangeable are parts from the two cars? Crudely, is the 309 the saloon version of the 205? Is it quicker to list the differences rather than the similarities, or are the bodies fundamentally different?
I ask as I am looking for some 205 spares - and wonder if I should look at 309 parts as well. Things like bumpers, front wings, doors etc.
I'm guessing this may have been discussed on several different threads for specific parts - but a search hasn't found me the 'big picture' answer
