25: 2003 Saturn ION
The Ion was the first new compact Saturn to have a completely new design. For 2003, it was shared with other vehicles in the GM portfolio. The ION was not an original car the first Saturn models had been, and this was a disappointment for some loyalists. The ION was also lethargic when it came to the performance (via Forbes).
The interior was cheaply made, and none of the unique safety features were present in the car. As time went on, GM would try to refresh the ION, but it wasn’t enough. The car couldn’t get over the hurdles of the lackluster design.
