That would be hard for me.... I love Evo's but it's hard to take them seriously. No offense to owners but I.M.O they just scream young tuner kid, and not serious performance car despite it being a better overall performer out of the box. Then again, an STi with the big wing kind of has has the same effect....
It would be a toss up for me, but i'd probably go for a wingless (or small wing) STi for overall quality, sound and curb appeal for any age
