The new
JCW seats retail at roughly £1750 for the leather ones, and £1850 for the alcantara ones (and then most dealers will charge £200 for fitting if you need it - i think you have to have the seatbelt sensors recoded otherwise there will always be a seatbelt warning light on).
Alternatively Chris at Woodman BMW, one of the sponsors of this forum does them at a special price of £1525 for leather or alcatara. (see:

Im hoping to get some myself, as ive heard they are some of the best seats available on any car.
