Wow, that looks reasonably nasty, I assume you rolled it? Its weird, how comes the door aint bent? Did it pop open as soon as it flipped?
At least you didn't get too hurt. When our drummer rolled one of his vintage mercs, I was the passenger and I got a couple of broken ribs and took out the side window with my head. Ironically enough, the broken window that I broke with my head was the most serious damage to that car, despite it rolling. I guess they made strong cars back then.
