One of the two sport packages. Don't miss out on the sport seats!
If you use an iPod/MP3 player a lot, get the Nav. It will be MUCH easier to navigate though albums and the iDrive control is in a very natural position. Also, if you do enjoy music, be prepared to upgrade the standard system or pay for the HK upgrade. After a few EQ tweaks, I'm almost totally satisfied with the HK in the 135.
I added the Premium because I can't stand it when someone moves the seat and I lose my driving position. I can never seem to get it 'just right' and the memory seats saves my sanity.
