27. Pontiac Aztek
Introduced in 2000, the Aztek was a good idea, at least on paper. This mid-size crossover had sharp new styling, a decent engine lineup, and plenty of interior space. Pontiac was eager to present it to the public since the overall sales of the brand were not great. They thought a new model would boost their popularity and bring new customers to dealerships. The plan was sound except for one thing: the design. Somehow, Pontiac designers managed to draw and push to production one of the ugliest cars ever made.

Every design component was deemed repulsive, and the interior was also questionable. The Aztek designer later designed the Corvette C7. It was bizarre how he managed to do such a lousy job at Pontiac. The pure horror of the car and not great fit and finish quality sealed the faith of the Aztek despite some good aspects of this model (via Car & Driver). In recent years, Azteks have been popular due to their appearance in the cult TV show “Breaking Bad” and first places in many “ugliest car” lists. Unfortunately, the failure of the Aztek affected Pontiac as a brand. A couple years later, Pontiac closed its doors for good.
