We see a lot of rare vehicles out there, but we don’t always come across the ones that are the only one in the world like it. This 1971 Plymouth ‘Cuda Convertible in Curious Yellow was part of a pack of less than 20 440 6-BBL ‘Cuda convertibles to be produced that year. That’s impressive enough, but there are even more reasons that add to the rarity of this beauty in particular, though. See what makes it so unique and how you can buy it!
