Ten of the most sought-after classic muscle cars in no particular order are the Chevrolet Chevelle, Chevrolet Camaro, Plymouth Superbird 440, Plymouth Barracuda, Plymouth Roadrunner, Shelby GT500KR, Oldsmobile 442, Pontiac GTO, Dodge Charger R/T 440 and the Buick GSX, according to The Richest. Muscle cars are basically medium- or full-sized family cars that are outfitted with a powerful engine, and are mainly for street use and drag racing.
Stock-car racing and drag racing played important roles in the development of muscle cars. Racing fans' interest in speed and power led to the creation of what many credit with being the first muscle car, the 1949 Oldsmobile Rocket 88. It housed a powerful high-compression overhead-valve V-8 engine in a lightweight Oldsmobile body. GM's Cadillac division came out with a V-8 for 1949 as direct competition against the Oldsmobile, but the GM vehicle could not compete with the lighter and smaller body of the Oldsmobile. The Rocket 88 went on to win eight out of 10 races during the 1950 NASCAR season.
Muscle cars grew extremely popular throughout the '60s and early '70s with Dodge, Chrysler, Plymouth and Ford battling for dominance in the world of drag racing. Muscle cars had a revival in the 2000s with the 2004 launch of the Pontiac GTO in the United States. Chrysler released the 2005 300C, Ford released a new Mustang that resembled the 1964.5 model in 2005 and in 2008 the Dodge Challenger, which featured pattern designs similar to the 1970 model, was released.
