5: 2000 Chevy Impala
After the Impala SS hit in the ’90s, it was hard to replicate a car that garnered that kind of a following. Nevertheless, GM decided to try and revive the nameplate once again. Thus the Impala was brought back, although this time it was a watered-down family sedan. The tried-and-true GM 3800 V6 was the standard engine and the car had some interesting features like a bench seat in the front.

But the car never managed to captivate the buying public, and quality was inferior to Toyota or Honda. Chevy has never managed to win the vast majority of family sedan buyers and the cheap quality of the Impala was part of this problem. The Impala never managed to improve much after this initial car was released.
