[Aerkuld]

Looking at the outline on the C pillar I would expect to see the back look more 911'ish on the real thing. I'd guess the back end will be a lot lower than that bulbous monstrosity. The huge bumper and duck tail exagerate it even more, I'm sure it's a deliberate attempt to hide some fairly graceful curves.
It's funny looking at the side shots how they appear to have made an outline for the windows in black and white tape to try and hide the true outline.
