I have the hatch rattle. My passanger door squeaks (down by the speaker). My roof rattles around the dome light. The plastic sheild in front of my gauges rattle BAD (fixed it by wedging a piece of paper in the corner to keep pressure on it). And to top it all off my suspension squeeks when going over bumps at slower speeds.

Best thing I've found is go in and glue all the screws you know you wont need to take out again with hotglue. Especialy around the speakers and inside of the door. And make sure everything will last the test of time. Lay down some rubber pieces where needed. Tighten everything up. As for the squeaky suspension, I'm dropping my car right after I get the cat-back exaust, so I dont really care too much.
