The windscreen seal has failed. Water leaking into the overhead lighting fixture and main cabin. This will ruin the car, and shouldn't happen to any car. The windscreen, when properly attached to the body, contributes to the structural integrity and crashworthiness of the vehicle. If the screen is only partly bonded, any stress could detach it and the upper part of the body would suffer reduced strength integrity. I can push the windscreen out with my hand.
