I just found a very nice German commercial for the 1 Series:
The clip obviously wants to communicate that the 1 Series is the only car with rear-wheel-drive in it's class. Very cool idea if you ask me. The text at the end says "The BMW 1 Series hasn't got front-wheel-drive. Now you know what makes it so sporty".

The video reminds me of another ad by BMW, this time a printed one:
If you can't read the text, it says "That's why we dont have front wheel drives" :)
