First of all, another
for the manual! Mine will be a 6-speed, too.
While we're discussing quandaries about options, here's my two:
1. Integral Active Steering
I had the original Active Steering on my 2007 335i coupe. Loved it at low speeds (so maneuverable!); hated it at high speeds (how come fast lane changes are so sluggish??). Anybody wanna comment on the new system with the rear-wheel steering?
2. Interior color
I'm planning on a Carbon Black exterior (550i M Sport). Not sure about the interior. I'm not a big fan of aluminum (or aluminium, for our UK friends!) trim so I want wood trim. IIRC, you can't get the dark wood (which I like) with the M Sport pkg.
One contender is black Nappa. The light wood looks silly with the black leather, and the anthracite wood + black interior + black headliner makes the whole thing look like a black-and-white photo. (Full disclosure: my M3 is all black -- interior, exterior, headliner, even the black woven leather trim. My boss calls it "Darth Vader's M3" -- and I think I'm bored of it.)
My other thought is cinnamon Dakota leather. I had that color in my 335i -- loved it; got many compliments. For anybody who has it, what did you do for trim??
