1970 Plymouth GTX Price: The Gentleman’s Muscle Car Cost
The 1970 Plymouth GTX received a significant restyling, featuring cleaner side panels and updated front and rear designs. Notable changes included a unique “telephone receiver” grille shape and revised tail lights, while the convertible option was discontinued. As a key model in Plymouth’s “Rapid Transit System” (R.T.S.) performance lineup, the GTX aimed to excite buyers not just with power, but also visually, offering striking “High Impact” colors like In Violet (FC7), Limelight, and Tor-Red. This combination of style and performance factored into the Plymouth Gtx Price positioning it as a premium offering.

To further promote the GTX and other R.T.S. cars like the Road Runner and ‘Cuda, Chrysler-Plymouth dealerships hosted special “Supercar Clinics” featuring racing legends Sox & Martin and Don Grotheer. Known internally as “RS23” models, every GTX came equipped for performance with standard heavy-duty shocks, suspension, driveshaft, U-joints, rear axle, battery, and brakes. Six-inch-wide wheels, bucket seats, and the distinctive “Power Bulge” hood were also standard fare.
Performance Pedigree: Engines and Features
Under the hood, the 1970 GTX offered potent engine choices. Standard was the “Super Commando” 440-cubic-inch V8 delivering 375 horsepower. Optional upgrades included the legendary 426-cubic-inch “Street HEMI®” V8 rated at 425 horsepower, and the formidable 440-cubic-inch “Six Barrel” V8. Plymouth badged this triple-carburetor engine as the “440 Six Barrel” or “440+6”, while Dodge called its version the “440 Six Pack.” Rated at 390 horsepower at 4,700 rpm, this Mopar® powerhouse featured three Holley two-barrel carburetors (350 CFM center, 500 CFM front/rear) delivering a total flow of 1350 CFM. High-performance engines of this era were typically painted Orange. Transmission options included the robust TorqueFlite® automatic or a heavy-duty 4-speed manual, paired with a standard 3.55:1 rear axle ratio.

Understanding the 1970 Plymouth GTX Price Point
Marketed with the tagline “No brag. Just fact.”, the GTX was positioned as the “Gentleman’s Muscle Car”. Owning one signified an appreciation for refined power. This premium positioning was reflected in the Plymouth Gtx Price. With a base price of $3,535.00, it cost roughly $600 more than its more basic sibling, the Road Runner. This price difference largely explains the disparity in production numbers: fewer than 8,000 GTX models were built for 1970, compared to over 40,000 Road Runners.

Optional equipment further influenced the final cost. The specific example featured selected the TorqueFlite automatic transmission and optional 15-inch wheels fitted with F60-15 Goodyear Polyglas tires. Additional options like power disc brakes, power steering, and an AM radio brought the total retail price for this particular car, including destination charges, to $4,193.70 when new.

A Closer Look: The “In Violet” FC7 Example
The specific 1970 GTX highlighted here is a factory “FC7” car, finished in the highly desirable High Impact color “In Violet Metallic”. Its value is further enhanced by sought-after options including the “E87” 440+6 engine and the functional “N96” Air Grabber hood scoop, which operated via vacuum. This example also features factory-optional white side stripes and a black hood stripe, complemented by a center console inside.

Rarity and Collectibility Factors
Well-documented Mopar muscle cars, especially those originally painted in High Impact colors, are highly collectible today. This particular configuration is notably rare; only 328 examples of the 1970 GTX were produced with the combination of the 440 Six Barrel engine and the TorqueFlite automatic transmission. Experiencing the full force of those three Holley carburetors opening up embodies the spirit of Plymouth’s Rapid Transit System.
