Exterior looks a tad bit anonymous - doesn't quite have a unique "5 series" identity any more. Too much of 3 series in some places, too much of 7 series in other, etc. However, for some people, the anonymous looks might be a good thing.
Interior is amazing, except for that hideous brown leather, but I'm sure there's going to be a limited number of people ordering that.
I'm eager to see these cars on our roads. I suspect darker colours might look nicer too, but that's subjective.
