This morning, I got into my 2002 530 and wnet to put something in the back. The carpeting in the rear passenger seat was wet. I took the floor mat out and it was soaking wet. It did rain hard last night here in the NY area, but all the windows, and sunroof were closed tight and everything else was dry. There was not thing to indicate what happened. Any one have a clue? this is really bizzare. thanks.
