I was driving home a couple of weeks ago on a surface street when I heard a loud bang from the rear drivers side. I thought i had run something over and thrown it up in the wheel well, which is exactly what it sounded like. The next morning i notice this on my C pillar. looks like highpwered airgun or very week .22. It did not penetrate the metal but put a good dent in the metal and seperated the paint from the metal.
