1. 1970 Plymouth Hemi ‘Cuda
The 1970 Plymouth Hemi ‘Cuda is the holy grail for muscle car collectors. With only a handful produced—especially convertibles—its rarity and monstrous 426 Hemi engine have elevated it to legendary status.
At recent auctions, pristine examples have shattered expectations, with one selling for over $2 million (source). Comparable models like the Dodge Challenger don’t command nearly as much, cementing the ‘Cuda’s status as an ultimate collectible.
