ICE -In Car Entertainment

My company has very kindly allowed me to pick my own company car (woohoo!) and I've narrowed it down to a few makes/models after test drives. I'm not particularly knowledgable about cars which is why I'm here to get feedback from more knowledgable people (aka you).

Criteria are:
Efficient running costs (fuel consumption, maintenance costs etc etc)
Driving experience.

Makes/Models:

#1 BMW 320i
#2 Audi A4 1.8 TSI (comes with Bang & Olufsen as standard :D)
#3 Volkswagen CC
#4...
