I think by definition car thieves are morons. A buddy had an Audi with a factory stereo. They busted his lock only to get into the car to realize that it's next to impossible to remove without the proper tools, it's says "Audi Design" on it, it will only fit THAT model of Audi (probably not on their minds), so they emptied the glovebox and storage areas to find nothing to steal except for some maps and mints and went on their way. Successful heist!
