Hi all, first post. How 'upgradable' is the STI? I mean, is it just about maxed out performance wise and near the ceiling of what it's capable of? Or is there a lot of room for improvement with aftermarket products. I'm curious because the main thing that attracts me to this car is the fact that you get so much bang (power) for the buck and if there's still a lot of room for performance improvement, better yet
Also, does the STI come with a sunroof? I think it's standard on the WRX but I haven't seen anything about it on the STI.
