Don't know about the trunk, but I have a leak in the front, on the driver's side, dripping on the parking brake. The water comes down from inside the dash. I finally figured out with some help that the leak comes from the right hood hinge well, which is rusted on the inboard side. Water going down on that side ends up in the cockpit, even though the drain is OK (water doesn't accumulate).

Hope this helps.
