My greenmetallic K 70 once was broken off. The damage was fortunately not too big, the door-lock was pierced. From me was stolen only an quite empty sports-bag with nothing valuable inside. But from my friend, who was with me, they took a bag full with original K 70-brochures, which he wanted to give to the others. Surely they were thrown away later.
Some more K 70 were broken off, too. We went around for a sighseeing-walk. It happened in Holland, in Roermond. We also were sure, who was it. some Arabian teenagers, which hang around there. The policeman told us, that this dark, unwatched parking was well known for that things.
The place is gone now. Now threre stands the big, well known Roermond outlet-center.
Once my NSU 1200 C was damaged. But unintended, I would say. Its engine-hood was, typical for NSU's, stood always open (I cannot count, how often the people had given signs to me: "Your trunk-hood is open!!"
)
One night, the cars stood on a parking of a disco. When I came back, the hood was bended and not close again. I would say, some (probably drunken) guys wanted to look inside, had opened the hood, but couldn't close it any more. NSU's have a hidden holding-bracket, which had to be released for closing.
