I have some water leaking into my trunk, apparently only in heavy downpours (unfortunately, I live in south Florida). It used to leak in all the time until I changed both tail light assemblies. Anyway, I was checking to see how wet it was in the trunk today, and as I lifted up the trunk mat, I uncovered to my complete shock and horror a breeding ground for big black and red ants!!! I haven't seen any inside the car itself, just inside the trunk. My trunk is now naked and doused with RAID and bait traps. I ended up throwing out all of my trunk lining (combination of water damage and heebee jeebees). I'll be tending to the leak as soon as I find and remove all of the ant carnage. I guess I'll just have to temporarily turn my 635 into my daily driver (oh damn).
