Nowadays, some of these Plymouth muscle vehicles are extremely valuable.

The vehicles serve as a reminder that the brand was discontinued. 

Certain cars, like the HEMI Cuda and the AAR Cuda, still have very good 60 mph times. 

The 1967 Plymouth R023 GTX and the 2000 Hennessey GTX Prowler are the quickest

production Plymouths, however many are extensively modified for drag racing. 

Arguably the fastest muscle car of the 1970s, the Chevelle SS454 was a direct rival of the Plymouth.
