Golf GTI Revealed

Now for my designer's opinion.

Outside = Yawn. At least the Mk5 and 6 had a touch of an agressive flavour over the regular Golf models. While different, this just looks, well, boring. Fins and flutes should have remained on 1980's supercars.
The interior looks like a regression in design. The mk6 interior I would argue looks more modern and cohesive than this model.

The front looks like a hippo has squashed it and the angularity of the DLO doesn't match in with the overall bubble-like shape.

but hey, that's just me
