They are totally different cars, built with totally different intentions, to fill two totally different segments of the market.
I'm sure his car does well in the twisties w/ all wheel drive and that much hp, but I wouldn't give up all the ammenities, build quality, and one hell of a torquey powerplant to spin all four wheels at the same time.
This rant isn't really targeted at you, I'm just sick of everyone judging the WRX based on stats in a magazine. I've driven one, and just wasn't all that impressed. It's quick and handles nice, but the car is not made all that well, and the interior is just plain cheap.
At $30K, I would take an R32 over an STi any day.
BTW, if he does beat ya, just tell him you were busy fooling with the heated bavarian leather seats :nana
