Rare four-speed 1971 Plymouth Hemi GTX shattered auction records after selling for more than $530,000 recently worldwide.
Just a few days ago, reports surfaced about an incredibly rare 1971 Plymouth GTX heading to the Mecum Indy 2026 auction block. Now the results are official, and the Hemi-powered Mopar ended up making history after selling for nearly half a million dollars before fees.
The final hammer price landed at $490,000, though that number doesn’t include Mecum’s 10% buyer premium. With fees added in, the total climbed to roughly $531,000, making it by far the most expensive 1971 GTX ever sold at auction.
The previous record was set back in 2020, when a Bahama Yellow example brought in $374,000. That particular car featured a factory sunroof and had long been considered one of the most heavily optioned 1971 GTX models ever built. Even so, the Winchester Gray example sold at Indy 2026 now stands as the highest-priced GTX ever auctioned, regardless of model year.
So what makes this particular Mopar worth so much money? For starters, it packs Chrysler’s legendary 426-cubic-inch Hemi V8, one of the most sought-after muscle car engines ever produced. The 1971 model year was also the lowest-production year both for the GTX and for Hemi-equipped versions specifically.
Plymouth launched the GTX in 1967 and continued production through 1971. Unlike the more affordable Road Runner, the GTX disappeared once Chrysler abandoned its high-compression big-block V8 program. Because of its higher price, the GTX never sold in huge numbers, with only 44,178 units produced over five model years.
The 1971 version proved especially rare, attracting just 2,942 buyers. Out of those, only 30 customers selected the 425-horsepower Hemi engine. Production records indicate that 19 examples came equipped with the three-speed TorqueFlite automatic transmission, while only 11 cars left the factory with the four-speed manual gearbox. This car belongs to the much more desirable manual-transmission group.
And there’s another detail that makes the car even rarer. The original owner checked the box for the optional Super Track Pak package, which added a 4.10 rear axle ratio. Experts believe only four cars were configured exactly this way. It also wears GA4 Winchester Gray paint, considered one of the rarest factory colors available for 1971. There’s a strong chnce this Hemi GTX is truly one-of-one.
The car later underwent a rotisserie restoration performed by Mopar specialist Dennis Kohr and still retains its original numbers-matching engine and transmission. It also came with the original broadcast sheet and factory window sticker, details collectors love seeing on high-end muscle cars.
Even though it became the most expensive GTX ever sold, this Mopar wasn’t among the top-selling vehicles at Indy 2026 overall. Several cars crossed the auction stage for seven-figure sums during the event. Still, this new GTX record will prbably stand for years to come.
For anyone wanting to watch the sale unfold, the Hemi GTX appears around the 4:02:23 mark in the auction broadcast video.
