In this case we have a bunch of people arguing about which ad is more clever, while nobody seems to have anything to say about why I might want to buy either vehicle.
Am I really supposed to put $75,000-$150,000 down for a car, and when somebody asks me why I chose it, say "Their ad made the other company's ad look silly?"
Claim BMW is playing the wrong game. Come back with something like: "King me," as an allusion to checkers, and then a quip about choosing Audi being the clear and simple choice.
