It's the Oz? Whoah...those are really rare. They're a special edition for rallying like teh crazy. I'd say it would absolutely kill a WRX - stock or modded - from a roll or dig. It has FWD, so none of those nasty drivetrain losses. Plus, they have ZERO turbo lag!11!! Prepare for a humiliating a$$-ravaging loss if you take him on. Good luck.
