Plymouth does not build many cars like the Plymouth GTX: a 2-door hardtop / 2-door convertible with 426 cuin Hemi V8, built from 1967 to 1971 in the decade that gave the world the pony car and the mid-engined supercar. Its designer of record is John Herlitz.
How it came about
The Plymouth GTX is an automobile manufactured by Chrysler and marketed under its Plymouth division from 1967 to 1971. Introduced as the Belvedere GTX, it was positioned as a mid-sized upscale-trimmed performance muscle car through the 1971 model year.
The hardware
Under the skin sits 426 cuin Hemi V8; other versions carried different engines, listed in the specification table below. The gearbox is a 4-speed manual / 3-speed automatic. The layout matters: a front engine drives the rear wheels, the classic proportion — long bonnet, cabin set back — that most people picture when they picture a sports saloon or a grand tourer. The wheelbase is 116.0 in. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Family and rivals
Where it sits in Plymouth's history is not in doubt: it was built at Detroit, Michigan (Lynch Road Assembly), United States. On a showroom list of its day it stood against the Pontiac Firebird, the Dodge Charger, the Lamborghini Miura. Its Plymouth stablemates include the Plymouth XNR and the Plymouth Laser.
The money
There is no federal ownership record for the Plymouth GTX — it predates the complaint database or was never sold in the United States — so MotorJury publishes no running-cost figure for it. For a car of this age the price is set by the collector market and the condition of the individual example, not by a formula.
