In pictures, the Mercedes Gran Turismo Vision real-life video game car looks like a giant dildo. In person, it's actually pretty cool, as this 360 view shows.
I maintain that this concept is utterly, utterly devoid of any brand identity and that the only thing that makes it a Mercedes rather than some aborted Daewoo concept car is some silver paint and a three-pointed star. Still, it is low, aggressive, and reasonably crazy. Hard to argue with that.
