Gents,
I recently purchased a brand new M Performance: Alcantara w/Carbon Insert Steering Wheel. I have the factory fitted, Sportline Steering Wheel for sale. It is thicker than the stock (non-line) steering wheel, but isn't as thick as the M Performance or M-Sport steering wheels.
Happily sell it for ono $500 - make me an offer!
Cheers,
Zender
