Plymouth Superbird Hemi – $1 million
Perhaps more notable than the Charger Daytona was the Superbird Hemi which fetched a cool million on the auction block. The Superbird Hemi was the car that Plymouth won many NASCAR races with. Richard Petty made the Superbird famous in what was dubbed the “aero wars” of the 1960s and 1970s. Cars were becoming more aerodynamic to win the races (via Work & Money).

The Plymouth Superbird was among one of the most famous cars in the muscle car era. Its styling and performance of it were unlike anything else that was on the market. There were competitors, but never anything that came close to the quality of the Superbird when it came to performance.
