Buy from a Ford dealer. I bought a Ghia 56 plate in October with no end of problems – a real Friday pm car! At first I was told that I couldn't have my money back and to change I'd need to give them £1k for "usage", however, after advice on here (thank you chaps) I spoke to the local Manager and he apologised and I collect my Climate 07 with half the mileage on Tuesday. Even after this grief I think they're great cars and yes, the heated screen has been so welcome of late.
Get one but from a dealer.
