[F30AM]

@Tengocity:
The Alpinas run on non run flat tyres, have a much, much better ride even on the 20" wheels which I hate the look of. If you want an LSD you can get a Quaife LSD from Birds for xDrive and sDrive cars. I also feel that the steering wheel is not as elegant as the M Sport one + the Alpina badges are very 70s in looks. Yuck. Very pricy proposition but there is a lot of hand re-building involved. It is supposed to be a brilliant drive.
