It certainly is unique! Sort of reminds me of what dodge did with the charger a couple of years ago with the squarish style and smaller windows - makes it look like a mobster car. The backseats certainly look more comfortable than any others. I don't know if I'd like a tailgate that swings to the side though. Seems like if you were to do any enginework - the hood would be in the way.
Score one for uniqueness though
Of course, that'* what concept vehicles are all about.
