The lower roof line appears to be a LOT more than the 2.7 inches - it makes a dramatic difference to the sportiness.
The taillights are fantastic, as is the sharper crease on the top of the trunk (instead of the double-crease).
And the more aggressive rear fenders are all win.
The interior will be the same, essentially, once stripped of all that individual crap. Though I notice the temperature dial is gone - good riddance!
I'm a huge fan of this new style.
