I have the usual water in the trunk in the left compartment below the jack - replaced the rear light gaskets and the antenna grommet. I left a blanket under the trunk gasket that was bone dry while the compartment by the spare tire jack was flooded. Possibly the sun roof drain tube leaking? I haven't noticed any water in, near or around the rear seats/rear floor/ or anywhere else in the trunk except the lowest compartmeny by the jack. Any ideas? I also have water coming in at the front seat passenger's left calf - it comes in under the trim piece on the transmission tunnel. If I drive it through a car wash I get soap bubbles pouring in there. All the trim/gaskets on the outside and around the windshield looks good. Any ideas? I'm new here - but I drove my 1987 325 off the lot new in April 1988 (the last 87 model on a lot full of 88s) - it's still my daily driver that runs great and looks great. In middle school I took a mechanical shop class - all I had to do was rebuild a lawnmower engine. It never ran again and I was scarred for life, so no major teardowns are possible on this car without some adult supervision!
