Introduced for the 1967 model year as a high-end variant of the two-door Belvedere, the GTX quickly earned the reputation of being the “Gentleman’s muscle car.” Although it may not have had the sleekness of its premium corporate sibling, the Dodge Charger, it did come with Mopar’s most potent V8 engines.
Upon its debut in late 1966, the GTX featured the formidable 440-cubic-inch (7.2-liter) V8 as standard. Those seeking more than 375 horsepower could opt for the mighty 426-cubic-inch (7.0-liter) HEMI V8, which boasted 425 horses. In 1970, Plymouth introduced a six-barrel version of the 440 V8, delivering 390 horsepower.
Unlike its platform mates, the Belvedere and the Road Runner, the GTX had a relatively short existence. The nameplate spent only five years on showroom floors before Chrysler began phasing out its high-performance engines in late 1971. The GTX wasn’t a particularly popular model either.
While the Road Runner sold 43,295 units in its first year on the market, the GTX moved roughly 55,500 examples over five model years. 1968 marked the nameplate’s best year, with 17,914 vehicles produced, whereas 1971 saw only 2,942 units roll off the assembly line. Notably, the GTX remains relatively common today, but the HEMI version is quite rare.
This rarity is due to the fact that only 1,526 customers selected the range-topping engine option between 1967 and 1971. This figure includes cars shipped to Canada, accounting for only 2.7% of the total GTX production. The most common year for the HEMI GTX was 1967, with 733 examples, but sales dwindled to less than 100 units per year between 1970 and 1971. Specifically, Plymouth sold 76 cars in 1970 and a mere 32 models in 1971.
The 1969 version featured here is relatively less rare, but you’re still not likely to come across one very often. HEMI sales dipped to just 224 vehicles that year, and this particular GTX is one of 208 sold in the United States. Furthermore, it’s one of 197 hardtops and one of 98 vehicles in this body style that also came equipped with a four-speed manual transmission.
But it gets even better. This GTX has undergone meticulous restoration, with the hardtop being immaculate both inside and out, and the engine bay in pristine condition.
Furthermore, this GTX is a numbers-matching car, with both the HEMI V8 and the gearbox bearing the correct codes as proof. Additionally, the color combination is both eye-catching and incredibly rare. Although it may not be one of the intense high-impact colors introduced by Chrysler in 1969, the Q5 Seafoam Turquoise is just as appealing as Vitamin C and Rallye Green. This GTX features a Seafoam Turquoise exterior, complemented by a white vinyl top and a white interior.
Moreover, this color is even rarer than most High Impact hues. While a few 1969 Plymouths can be found in this color, this HEMI GTX in Seafoam Turquoise is only the second one I’ve come across. There may be more out there, but until another one surfaces, this HEMI GTX could very well be a one-of-two classic, and it commands a price tag of over $200,000.
