10: Chevrolet Monte Carlo (1973-1977)
The second generation of the Monte Carlo had trouble justifying the price tag when it was new, much less 40 years later. The 1973 model was a huge departure from the Chevelle-influenced car that came before it. How much changed you asked? Well, the body paneling looked like a stretched version of the previous generation.
Aside from that, the performance was vastly underpowered due to all of the new emissions laws. Like with most cars from this era the automakers were just starting to adapt to all of these changes and it didn’t end well for the consumer.
