A (german) song about a broken car. I guess you get the funny side of it even if you dont understand german. Its a real performance to make a 5 minute song about a broken car.

I haven't watched the fully video, so for some rarities and specialities, you have to look by yourself.
@dsl: there is a guy from the

to see. The museum, which owns a "made for DDR" Hillman Minx, but without any background informations about the circumstances of this deal with Britain.
