I'll be picking up my new Impreza tomorrow. Anything I should know? I want to install rallyarmor mud flaps (is that easy enough by the way?). Should I make any pointed upgrades to a premium model? Also, can anyone recommend any nice wheels that look better than the 17's the upgraded premium comes with (they have to be pretty cheap)? The ones on it are merely nice...I was looking for something with a more sport premium feel, or at least a darker more subtle look than the flashy silver wheels.
