Looks are a bit divisive, but the car grows on you. It's still relatively lightweight, weighing in under 3500 lbs so for all the size of the car it certainly shrinks around you when you drive.
My only real con is that the suspension has a lot of slop. It works on the road but on the track it's going to shred the front tires with all the body roll.
Can't really think of any cons against it -- it's finally the grown up WRX that it was always meant to be. The lack of a wagon would be a con, but like the manual transmission it's not really something we're going to find in North America. Wishbone rear does wonders and the engine has the power the car was always meant to have. The turbo I assume is the same as the WRX, just located in a better position. Car has an enormous amount of low end grunt now, almost comparable to direct injection engines.
It's a great car that is comfortable commuting but won't bore you on the weekends.
