My Xfire has a ridiculous amount of rattles and squeaks. Go ahead, push against the door panels, I dare ya!! Oh, don't forget about that ridiculous hatch! I had to use double sided tape on the stops to keep it from rattling even after adjusting them all the way down!

Just don't ever do this to your 'vette!!!
