I saw the thread about this before I got my car. First thing I did was check for that when I washed my car for the first time.
It's dry. However! On the day I got my car I found the weatherstripping on all my doors except for the driver's door was rolled out of place. There's a holder thingy that pokes into a hole but it seemed to have popped out so the weatherstripping rubber wasn't sealing properly.
Check that and push it in yourself to make sure!
