I had similar decissions.
In the end I ordered the Msport in the SD. Even though I don't get the car till late December, the dealer had a 4.8 sport in reciently and it looks so much better than they do in the pics. Yes the aero kit looks good but they are different looks and im sold on the sport, but each to their own.
I also went for the sunroof which as other posters say really brightens the interior. I don't expect to have it open much in the UK though. The Rev Camera as much as it seems to get a panning on the forums, for £250 has to be worth a punt just cos it looks cool.

Im considering the comfort access also. Its an expensive option here in the uk. How does it work if two of you have your keys on you and you each have your own setings? if the passenger gets in on the passenger side will it confuse it?

Anyone else considering the soft close doors or comfort seats over the sports ones?
