however, i cant seem to figure out the answer... did sport seats have motorized headrests? secondly, if so where is the button?
Do a search. A member here did a swap with the M3 headrestsanother question on this topic,
Are the electric head rests easy to replace? My frieind has ///M indented into his head rests in his E46 M3. I think its a nice touch and would like to get some if its a DIY and I can get hold of them. (don't know if that's standard or an option or a retrofit as his are manual).
