20: 2002 Mitsubishi Diamante
The Diamante was another letdown for the automaker that never resonated with consumers. It was a big sedan but the ride quality was lacking, and when it came to performance, it wasn’t there (via Forbes).
The Diamante didn’t have much going for it. The price was high and the features were limited. There were much better options on the market at the time and the Diamante didn’t have a place to fit in.
