There are many bad cars, there are many ugly cars, there are many cars that turned out to be failures (ahem Ford Edsel), so the competition is strong. However, if you were to poll anyone who knows anything at all about cars and ask them for their top 20 worst small cars aimed at the cost-conscious driver, these five (including variants) would be on everybody’s list. Shitty designs, woeful engineering, crappy materials, zero performance / handling, prone to bursting into flames: these clunkers had them all — proof, as if anyone needed it, that for some people, (low) price is everything.

In the case of the Trabi, it remains a monument to how Communism can screw things up: when essentially the same people can produce two totally different cars — i.e. Mercedes/BMW/Porsche/Volkswagen on one side of a Wall, and the Trabant on the other.
