OK, my 2 cents.
I really like the understated looks of a '12 in KBM. Not flashy, not flamboyant, just solid and conservative...with a bit of badass.
The '13 in DIB IS a little too flamboyant. When I first brought the car home, I asked myself "What one word best describes its appearance?" The word was "fabulous". Well, that wasn't the word I wanted.
The 13's bulgy GT500 looks are overstated as well; especially on a V6. Looks mean alright; but, c'mon. It's just a V6.
So I prefer the looks of a '12 in KBM to what I've got. But that's alright; I don't need perfect. The car has enough going for it that I can overlook a flaw or two.

I drive it like I own it.
