Sunroof drain - Fine wire. Get the seats and carpets out asap. Check the drain hols in the bottoms of the doors. When it finally stops raining there pull off as much interior trim as you find necessary and dry EVERYTHING out. You could even have water in the loom up to the dash cluster (capillary attraction). Water in looms does funny things. If you really want it dry - drive over here to Perth 33+ and dry as a chip. The kettle is on!
