5. Geo Metro

The Geo Metro was designed with one goal: deliver the absolute best fuel economy at the lowest possible cost. Lightweight construction and stripped-down features made this car honest to a fault—transportation, plain and simple. Unfortunately, that honesty translated to a reputation for being cheap, slow, and unsafe in the eyes of many buyers. While it excelled at saving gas, its minimalism alienated drivers who wanted more comfort or perceived safety, resulting in sluggish sales. Jalopnik
