I definitly think the A4 is the best bang for the buck. the BMW 3 series does have faster models if you are willing to spend the money and if you live where there is no snow the rear drive has some performance advantages until it rains or snows. But honestly i would go with the Audi they are slightly cheaper to maintain than the BMW and have a much nicer interior. I think for a every day driver its a great car if i was buying a track car i might consider the 3 series but not for a daily driver their just not as practical especially up north.
