Actually the video below is just a promotional effort for ClearPlex, a company that makes clear protective coating for windshields – a coating it is presumably showing off here (note that the apparent miscreants have no eye protection). The kids are not hoodlums, however, but rather actors (though we don't know if they were paid or simply did it for the enjoyment of breaking glass with baseball bats and tire irons), and judging by its setting, this GTI was likely headed for the crusher anyhow, though it looks to have lots of usable spares on it.
At the end of the video, the kids descend upon a brand-new Ford Mustang convertible. Do they go crazy on that car as well? You'll just have to click below to find out.
