Well lets see. 99% of the world don't know what an XT is so when they get smoked by it they'll think its just another Prelude or something. The Outback Sport doesn't look like a WRX so if you stick it in there you can go out and smoke the WRXs and the ricers will run back to the dealer asking for an Outback Sport
. Then again you did say its your wife's car. Put it in the XT. You'll enjoy it more.
