You might ask them if anyone feels like joining you for a spirited drive on a good snowy day, or perhaps down a few of your favorite dirt roads. Stoplight to stoplight is one thing, but consistantly good go, stop, and turn in all kinds of conditions is where it's really at.
Also, without spending like a king, a few judicious mods pay big divdends with the WRX. Yer car rocks. Ciao.
