8. 1977 Camaro Z/28
Like all muscle cars in the ’70s, the Camaro faced tightening emission and safety regulations and loss of power and performance. The early second-generation models looked promising, but just a few years after, the Z/28 was gone. The most powerful V8 model had something like 165 HP. A pale shadow of its former glory (via Auto Evolution).
However, the 1977 model is essential for two reasons. First, it marked the return of the Z/28 option after a few years of absence. The ’77 Z/28 had just 185 horses but it looked wild with a unique body kit, wild graphics package, and spoiler. However, the second reason is much more interesting. In 1977, Chevrolet Camaro finally outsold the Ford Mustang for the first time since 1967. The mid-’70s Mustang was a really slow and ugly car. While the Camaro at least looked much better with proper muscle car styling and stance. That is why Camaro sold over 200,000 examples that year alone, while the Mustang only managed to sell 153,000 copies.
