14: Pontiac GTO
In 2004, the Pontiac brand released a peculiar ride as the GTO was revived again. The new GTO was based on a Holden model. The Corvette-derived LS-series engine is quite the powerplant. The GTO is still powerful by today’s standards and can compete with modern muscle. From an off-the-line perspective, the GTO will easily compete with the Nissan Z (via The Drive).
Critics panned the styling, but this was before the retro-themed muscle car styling took over. Pontiac only sold the GTO for a short time before it was discontinued. You can find a later model example with a huge amount of horsepower. The GTO is also economical when compared to other muscle cars.
