11: Chevrolet Nova (Corolla)
GM has been in many different partnerships over the years but perhaps one of the longest-running and most confusing was the partnership with Toyota. This brought us many cars throughout the 1990s and 2000s, but the most disappointing was the Nova. GM took the well-respected Nova brand name and slapped it onto a compact Toyota Corolla (via Car Bibles).
About the only thing that was good about this car was the fact that it was a Toyota, which translated to reliability. Because the design of the car was quite cheap and the fact that the Nova name was tarnished like this was disappointing. GM would continue to sell the rebadged Corolla well into the 2000s, although it became the Prizm.
