As Pete says its each to there own. What suits one dont suit another.
When I bought my E90 new I didnt spec any kind of Nav/Media system. Not interested. Saved the £2K and put it towards other options that I wanted. The odd time I go anywhere I'm happy to use a Tomtom and for music I use a USB stick.
On the whole, for the F3X has a great sport auto 'box and visibility pack is great for the headlamp assist alone, let alone xenons etc...
From there on, its up to you want you think is important.
