4: Chevy Aveo
General Motors has sold some type of subcompact car since the fuel crisis of the 1970s. Anyone who knows anything about the history of cars knows that GM subcompacts have never been impressive. Cars like the Citation and the Geo Metro were sad and barebones at best, and then the Aveo came around. This car was derived from Daewoo engineering after GM purchased that company in the 2000s and the Aveo was a car sold around the world (via The Truth About Cars).
While the Aveo was light years ahead of the compact cars it replaced, it was still a minuscule subcompact. The reliability was questionable at best, and the styling was about as unmemorable as you could imagine. The Aveo was refreshed with a more modern design in the later years, but it wasn’t enough to boost sales. Consumer tastes were shifting and the Aveo didn’t resonate with consumers who wanted a reasonably priced subcompact car.
