Plymouth
Plymouth was Chrysler's value brand until the muscle era made it a legend: the Road Runner brought budget Hemi warfare to the masses complete with cartoon licensing and a 'beep-beep' horn, and the 1970 Superbird — its winged, nose-coned NASCAR homologation special — became one of the most recognisable American cars ever built. Hemi 'Cudas sit at the summit of the entire muscle market, with rare convertibles having traded in the millions. The brand died in 2001, but its 1968–71 output remains the beating heart of Mopar collecting.
Plymouth Hemi 'Cuda
426 Hemi-powered E-body Barracuda — the most valuable American muscle car at auction and an outright blue-chip.
Plymouth Superbird
Chrysler's 1970 NASCAR aero-warrior homologation — a Road Runner fitted from the factory with an extended nose cone and a towering rear wing, built for a single model year to bring Richard Petty back to Plymouth and legislated off the superspeedways after one season.
