1968 Plymouth GTX RS23 | 440 Big Block | 43k Miles | Bright Blue Metallic

This 1968 Plymouth GTX is a true high-performance Mopar muscle car, presented in Bright Blue Metallic over a matching blue interior and powered by a 440ci Super Commando V8. This example is the “real deal” RS23-code GTX, not a clone, and shows just 43,873 actual miles. Offered at no reserve, it combines factory pedigree, raw big-block power, and unmistakable late-’60s street presence.

The GTX was marketed as the “gentleman’s muscle car”—but make no mistake, with the 440 big block and TorqueFlite automatic, this coupe delivers serious performance with unmistakable attitude.
