No one really knows why this guy went so crazy, but he takes his anger out on an entire Nissan dealership with his car. Maybe his salesman was giving him too hard of a sell on the undercoating package.

Our favorite part is the guy who politely knocks on his window at the 2:10 mark as if to say, "Excuse me, sir, but you seem to be plowing through a car dealership. You might want to hit the breaks." Way to go, buddy.

On a positive note, no one was injured in this video. Well, no one except a few cars, some plate glass and a plant.
