The Plymouth GTX debuted in 1967 as an upscale muscle car, positioned above the more budget-oriented Road Runner. It came standard with the 440 cubic inch 'Super Commando' V8, with the legendary 426 Hemi available as an option. The GTX blended top-tier Mopar performance with more creature comforts, earning it a reputation as the 'gentleman's muscle car'.
Collectors prize the GTX for its combination of power, style, and relative rarity. Hemi-powered cars are the undisputed kings of collectibility, often commanding six-figure prices due to their low production numbers and incredible performance. The final 1971 models are also highly sought-after for their dramatic styling and being the last of the line, with fewer than 3,000 produced.
The market for the GTX is mature, with an average sale price near $48,000 based on 57 recent sales. While project cars can be found, top examples, especially Hemi convertibles or documented 'Air Grabber' cars, sell for well over $100,000. Well-preserved 440 cars offer a more accessible entry point into high-end Mopar ownership.
Buying Tips
- Rust is common in B-body Mopars. Inspect the rear quarter panels, trunk floor, frame rails, and the area around the rear window for corrosion or poor repairs.
- Verify the car's identity by checking the VIN. A genuine GTX starts with 'RS'. If possible, find a car with its original broadcast sheet and fender tag to confirm options.
- Hemi cars require extreme diligence. A lack of documentation proving its originality can impact the value by tens of thousands of dollars.
- The standard 440 V8 provides immense power and is significantly cheaper to own and maintain than a Hemi. Don't dismiss a solid 440 car.
Prices range from $2,500 for major projects to $162,250 for top-spec, documented examples.
