Pontiac Aztek
Introduced in 2000, the Aztek was a good idea on paper at least. The 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 could have been better. They thought this new model would boost the popularity of the brand and bring new customers to dealerships (via Car and Driver).
The plan was sound, except for one thing, and that was the design. Somehow, Pontiac designers managed to draw and push to production one of the ugliest cars ever made. Just look at it. Even 24 years after the first Aztek saw the light of day, it’s still a car with a design that makes no sense whatsoever.
