Like Archon says, were here to bother (or at least HE is)
Along the lines of his questioning, try to give us a better idea of where on the car the rattle is coming from. You'll probably find that, as you have a friend or someone help you locate the rattle better, you'll find it yourself. But if not, at least you'll have more info to help us help you (does anyone remember where that came from?).
Have you tried listening under the car for the rattle? (I.E. exhaust, linkage, etc.)
Or carefully listen at the doors themselves?
