28. 1971 Plymouth Barracuda Convertible Hemi 426
One of the rarest, most sought-after muscle cars is the Plymouth Hemi ‘Cuda. However, the Plymouth brand no longer exists. The 1971 Barracuda, or “‘Cuda,” is the second and last generation of this model. They redesigned it for 1970, featuring a new body and interior and a lineup of powerful engines. Since the Hemi option was extremely rare, this ‘Cuda had a 425, underrated horsepower motor that delivered a brutal performance. The convertible body style was also rare, so only seven Hemi Cuda convertibles came out in 1971.
The reason this was such a rare car was simple. Back in the day, a convertible with the most powerful engine wasn’t as desirable today. The Hemi engine was the favorite of the street racing crowd who wanted performance. So they installed this engine into the lightest body, which was a coupe. But Plymouth built this convertible for cruising, and for that, you don’t need a 425-thumping horsepower motor. This is why Plymouth only built seven of them. Since they are rare, the Hemi Cuda drop-top is one of the most expensive muscle cars ever. In fact, a mint 1971 ‘Cuda sold for $4.1 million dollars back in 2008. Although Plymouth offered the Barracuda or ‘Cuda until 1974, they discontinued the Hemi engine and convertible body.
