Pontiac GTO
The last generation of the Pontiac GTO was one of the most prominent examples of a misunderstood car. The Holden-built and LS-powered GTO was a proper muscle car that featured a powerful engine, sleek design, modern suspension, and brutal performance (via Car and Driver).
Despite boasting 350 and 400-hp engines and excellent performance, it never reached the sales numbers or success Pontiac hoped for. The 2004 to 2006 GTO could accelerate from 0 to 60 mph in less than five seconds and reach 175 mph, which is quite fast for a muscle car.
