I've always really disliked the shape of the K12, but there's one or two exceptions around in japan that aren't too bad. Though it has to be in white, with good rims to suit.
The K10 was too boxy for me, though don't get me wrong, the superturbo version was insane! The K12 is too bubbly and looks like they just started changing things because they could. The K11 however is very subtle and is such a nice car to drive/work on, which is probably the reason they're still so popular (at least with us).
