I've actually seen one Trabant on the road: on a Swiss freeway, shortly after the Wall fell. It was keeping up a good speed, so I suspect the owner had a new engine in it.
The body is of a compressed wool and resin mixture, and the engine is a three cylinder two-strok abomination. It sounds, and smells, like a lawn mower. Not too hard to figure out how communism is evil when you see the cars they produced. What's esp. damning is that if you wanted one, it was best to have your father request one when you were born. That way, by the time you were 18 or so, you might have a decent shot at getting one. That's right - they had a waiting list for this wonderful creation.
