Yup. US doesn't get the M-Sport. I think it looks great on dark color cars, especially black. But the aero kit looks good on lighter color cars where you can see the contrast with the black bumpers (ie: white, space grey, silver, etc)

Definitely buy the Aero kit from the forum sponsor dealership- Morristown BMW, see their section in the BMW related forums section. Then get it installed outside the dealership. You'll save yourself some $$$.
