That guy was obviously gay and had a run in with an exboyfriend or what not, regardless I feel sorry for the car. If someone does that, you'd have to have really pissed them off pretty badly. There is no way that was a random keyup, and after something like that who the heck would say " I was wondering if I will be able to take some form of legal action" that guy seriously needs to grow some. If someone does that, you shouldn't spend time on a bmwboard, you should go out and kill the person who did that.
Sure I feel sorry for the car, but im pretty sure hes responsible for that being done to his car.
