As a Manchester City supporter I can honestly say that it is one of the nicest and most striking colour combinations I have seen!
Bias aside, the owner is a brave chap/ette but it works very well. I would have been tempted to have a navy hood and navy piping on the leather to break up the light blue but as KEVFITZ says, everyone to their own, the interior of mine is pretty unusual too and not to everyone's tastes. I'm sure the new owner of the blue car loves it.
