Open the trunk. (Check Both Sides) Pull the trunk lining away from the rear fender walls. You should now see (on each side) a Black Plastic vent like square protruding. One of these black vents in mine was completely pushed into the fender leaving massive room for H2O to enter, the other side vent just wasnt working properyl (Each Vent have these plastic FLAPs outside allowing air to exit but not enter) Havent had a single drop since. (AIf your leaks seemed to accumilate only near the rear side walls of the trunk, this is 99% the problem) BTW use common sense to repair/replace/fix these, very simple. Later
