M Sport very specifically because:
- M Steering wheel
- Sport Seats (I have extendo-thighs)
- Black ceiling headliner
^ Would not buy a BMW without the above items
Aesthetically nice things that I don't care as much about
:
- Lit up M shift knob (nice look and improved feel)
- M bumper/rear diffuser (looks more aggressive)
- Estoril Blue II paint (would be nice to continue my blue streak)
- Black door trim (more sporty and "dark" vs. traditional/luxury look)
Things I don't care about
:
- "M style" rims (swapping them out anyway)
- M foot rest / interior door guards
Really it all comes down to this
