After driving both the petrol and diesel versions, I would say it is an improvement, but not enough to make me want to change from my MkV. It's a little quieter (more engine insulation and 10% thicker windows) and the interior quality is a little better (most notably on the soft touch rubbery dash top). The loss of the blue dials is a shame, but they thought white looked more modern. Overall, there are dozens of minor changes that are hard to spot (or make little difference).
The rear looks better on the road than the pictures as it makes the car look wider and lower. Interestingly, people who liked the MkIV and not the V, liked the VI more.
The biggest improvement is the common rail diesels. They are MUCH smoother (and lower emissions). The full body colour bumpers are in response to complaints and everyone wanting black cars to hide the cheap looking bumpers. Why they didn't make the MkV body coloured (like the ED30) I don't know.
