I looked at these guides again today and noticed one cool thing about MY2013: because the Sports Package has been deleted, BMW is not longer going to restrict the M-Sport Package to the most mainstream colors.
I find it very limiting that M-Sport can only be paired with select colors today. Unless I'm missing something, it appears that M-Sport can be ordered with every color except Black Sapphire Metallic, but that's probably because they're offering Carbon Black in MY2013.
Since I'll almost certainly have to order my car to get what I want (especially a manual transmission), I'm glad to see I'll be able to choose any color I want. Almost every BMW I see these days is white, silver, grey or black -- there's nothing wrong with those colors, but I like choosing the road less traveled (my current car is Blue Water Metallic). M-Sport Vermillion Red on Taupe is sounding good to me...
