I ve written the stuff down that I really wanted. Prices here (europe) are very high, so I really thought hard of the things I would really need/use. Some stuff I added while thinking practical (Navigation, heated seats) , then with the left over budget I ordered the stuff that I really liked...panoramic roof(I have that in my 325i touring aswell), 214 style 20" wheels and the Hifi Professional system.

I guess it is just a matter of taste & budget, and what for one person is a must, can be useless for another.
