6: Plymouth Barracuda
The original Plymouth Barracuda is perhaps one of the most unique-looking “pony” cars ever released. A fact that’s commonly missed by the automotive industry is the fact that the original Barracuda was released a year before the first Mustang generation. The Mustang is often credited as the original pony car, but the Barracuda was one of the first.
The sloping style of the Barracuda was a special feature of the car, giving it a very modern appearance. Plymouth was introducing several unique cars to the lineup, and the Barracuda was a step in the right direction. With the wrap-around back glass and the lightweight performance, the Plymouth Barracuda is a stellar muscle car from the original era. The values on these vehicles are going to continue to rise.
