5. Pontiac GTO
The last generation of Pontiac GTO was one of the biggest examples of a misunderstood car. The Holden-built and LS-powered GTO was a proper muscle car, with a powerful engine, sleek design, modern suspension, and brutal performance.
Unfortunately, it never reached the sales numbers or success that Pontiac hoped for despite the qualities, 350 and 400 hp engines and great performance. The 2004 to 2006 GTO could accelerate from 0 to 60 mph in less than 5 seconds and reach 175 mph which is fast for a muscle car.
