I don't know, I kind of like it.

Take that back - 'merican cars have a nice box shape to them that says "Aerodynamics - suck me - the wind can fucking go around"...

The rear of the 05 is one of the few parts of the car that I'd change if I had a magic wand - I'd remove all of the "wedge" from the car and have the line that connects the rear-deck to the hood almost perfectly parallel to the ground...
So, to make it even more Euro-wedge is a bit of a slap in the face to me...
