Thanks for all of your replies, I'm hoping I wont have to worry about it now as I have a garage to keep her in wherever I'm staying.

I just have to have the mirror fixed, I had someone have a look at it and the electrics are all still working, the mirror part and colour coded part are both in-tact so i'm hoping to get away with just replacing the broken plastic !

Every scrap yard I have contacted are asking £50-£80, which is not much different from what Ford are quoting, weird!
