36. Pontiac Aztec
Introduced in 2000, the Pontiac Aztek was a good idea on paper at least. This mid-size crossover model came with sharp new styling, a decent engine lineup, and plenty of interior space. It was a modern concept at the time. Pontiac was eager to present it to the public since overall sales for the brand were poor.

They thought a new model would boost the popularity of the brand and bring new customers to their dealerships. The plan was sound, except for one thing, the design. Somehow, the Pontiac designers managed to draw and push to production one of the ugliest cars they ever made. Just look at it. Even from this distance and 17 years after the first Aztek saw the light of day, it is still a car with the design that makes no sense whatsoever.
