a friend with a convertible had her top slashed and the top's frame bent - someone sliced into the top and tried to climb inside to steal her $40 safety inspection sticker. all they did was destroy the sticker rather than scraping it off, and the person's weight bent the top's frame, so she was out almost a grand.
the real kicker? HER DOORS WERE UNLOCKED! they never even bothered trying the door!
