Those VR6's are nice. My dad has the GLX, and it is fast. Granted, I've never driven a Wrx, so I can't really compair, but they are heavier compaired to my Outback, far from compairable handling, and they peal out easyily if you're too quick on the pedal.
Personally, I'm not surprised you got smoked by one. My pop's is all stock and it if still a whole lot of fun to drive, but would never I pick one over a Subaru. What's the point of all that power if you're afraid to lose traction? =)
