Bump from a fellow WRX owner.
Sweet ride. I still have and drive my 5spd wagon (technically the E90 is the wife's car). You will love the E90 it is SOO much more refined that the frantic little WRX, but I think you will always miss the grin
that you get from the Scoobie. There's something magical about WOT in 2nd gear in a WRX, that no other car I have owned can match. Good luck! Hope this is on NASIOC too.
