SOLD!!!
I have a used steering wheel from a X5M. It has the tri-color stitching, paddle shifters, and M-badged trim. No airbag. It should work in any X5 or X6. I was going to tackle this retrofit into my X5 but have decided against it (I would need to get a sport airbag (mine is non-sport) and figure out how to wire in the paddles).
It is in perfect like new condition.
$800 OBO
