IF you order the "full" M-sport option on any 128i/135i you get the black M Anthracite headliner, along with; sport seats, sport steering wheel, M door sills, M-design wheels(same size though) and M-shift knob. The option code was ZMP. It also included a raised speed limiter to 250 kph instead of 210 kph.
