Every once in a while Audi spends a big pile of cash and makes an awesome commercial. This is definitely one of them. The spot is about the rivalry between Leonard Nimoy and Zachary Quinto, the old Spock vs the new Spock. Audi likens that to the rivalry between the A7 and the Mercedes CLS. This being an Audi commercial, of course, the young Spock with his A7 wins the day, but many people still prefer the original.
