I keep my coupe on the street at the moment with what I thought was a grade-A waterproof cover. That turns out to be a poor assumption on my part. Car cover issue aside, I now have discovered a pool of water in the trunk to the left of the jack. The trunk seals etc are all pretty good with no debris or blockages visible. I can't see any obvious point where water would be seeping in. Like us all, I live in terror of the rust gremlins so where should start looking for leak points etc
