I bought a different steering wheel for my E92 M3, and will no longer have use for the original ///M steering wheel or its corresponding steering wheel cover. I am keeping the airbag, but if you have the M Sport steering wheel, you can reuse your airbag and steering wheel cover with this ///M steering wheel.
I've had the car for only a year. I condition the leather monthly, and most of my driving time is spent with leather gloves on. The leather is in mostly good condition, though I must add that there is a small scratch at the 4:30 position that you can see in the second photo.
My asking price for the steering wheel is $250 OBO (MSRP is $625.72 before tax). Price for the steering wheel cover is $100 OBO (MSRP is $133.62 before tax).
Shipping would be extra, but I am in the Los Angeles / Orange County area for those who would like to pick up directly from me.
