My brother is currently home from the UK. He has a 16 plate F30 320d MSport Touring xdrive as a company car.
Sport auto with paddles and all the toys. Gorgeous car. Got a spin in it and to be honest there isn't the need for any more power imo. It really launches with the 4wd and from 60-100 mph it flies along. Stick it in sport plus mode and it can tackle the twisties superbly.

If you could get an early one of those they are a beautiful car.
