Almost nothing. Driver's seat feels a bit loose and Ford wants £300 to replace the bracket. Uh huh.
Passenger airbag cover has popped up. Don't know how that happened. Nothing wrong with the airbag. It looks tatty, but isn't an MOT failure.
Gaskets around tail light lenses were letting a bit of water into the spare tyre area.
Windows are always fogging up... even without any noticeable water in the wheel well.
All minor stuff, really. Even has original clutch!
Sounds good, brilliant to drive... though I agree it can be a bit of a problem to park in tight spots... usually have to do a 3-point turn to get it in to a spot at the shops, but you get used to it after a while.
Finish is still good, even after 6 years of being left outside in North Yorkshire weather. Still a quick, smooth car that sticks to the road. BMWs are nice motors, I can't argue, but the ST24 can hold its own against a 325, has more room all around, and is far less nickable. And I like the look of my old ST better than the squarish new ones. Though I do like the ST220 colours.
I hardly think it fair that you consider the price of the Seat Bracket expensive. These are after all a Main Dealer Part. The Dealer has the expense of Ordering it, then Ford has the expense of Warehousing it until you Order the Part. This is why Main Dealer Parts are more expensive.
