The muscle car era of the 1960s and 1970s is renowned for its raw power, aggressive styling, and the exhilarating driving experience these vehicles offered. While many of these classic cars have become legends in their own right, some models were deemed too powerful, leading to their outlawing on public roads. Here, I take a closer look at seven iconic muscle-era cars that pushed the limits of performance and ultimately faced restrictions due to their sheer horsepower and speed.
