VDC for sure. It's great if you have the budget but you can definitely live without it. I have standard suspension on my M Sport (M Sport Suspension Delete) and it is fine. Great ride over the crap UK roads and fine on the motorway. Sport suspension on its own is also fine if you like a firmer ride and to lose your fillings on potholes
If you do go for Pro Media also add the following to get the most out of it:
BMW Apps
Telephone USB Audio Connection
Internet
..but don't worry they are all dead cheap.
