A widely cited $4.8 million figure from a later Hemi ’Cuda auction was a high bid on a car that did not sell, so it does not replace the completed-sale result.
Which HEMI-powered car holds the documented auction result?
The leading documented result is a 1971 Plymouth Hemi ’Cuda convertible sold at Mecum’s Seattle auction in June 2014 for a reported $3.5 million. Mecum described the car as an outstanding numbers-matching four-speed example and called the amount its “$3,500,000 selling price.” Mecum’s sale description identifies it as the highest price paid for a 1971 Hemi ’Cuda convertible at public auction; contemporary independent reporting by ClassicCars.com Journal also reported the $3.5 million winning bid.
The careful formulation is “highest documented completed auction sale identified here,” rather than an unqualified claim that every HEMI-powered car sold by every auction house has been exhaustively ranked. The available sources do not provide a comprehensive cross-house database, and they do not consistently establish whether reported figures include a buyer’s premium or refer only to the hammer bid.
Why the $4.8 million bid does not count as a sale
At Mecum Indy in 2021, a 1971 Plymouth ’Cuda Hemi convertible reached a reported high bid of $4.8 million but did not sell. Auction reporter Rick Carey’s account labels the result “Not sold at Hammer bid of $4,800,000.” Carey wrote, “Had that offer been taken, it would have been a record price”—a useful counterfactual, not a report of a completed transaction. Read the auction report.

An auction bid and a completed sale are different outcomes. When a reserve is not met and the seller does not accept the offer, the car has not been sold at that price. That is why the 2021 figure does not displace the reported $3.5 million 2014 sale.
How a later reported sale compares
Black Book’s February 2026 Collectible Cars Market Update lists a “1971 Plymouth Hemi ’Cuda Convertible (4-speed)” at $3.3 million for Mecum Kissimmee. That published figure is $200,000 below the 2014 reported $3.5 million result. See Black Book’s market update. The figures are reported results from different dates and sources; the available reporting does not establish a consistent price basis for comparing hammer amounts with totals that may include buyer’s premiums.

Do not confuse the record convertible with a different 2025 car
Mecum’s listing for a 1971 Plymouth Hemi ’Cuda offered at Kissimmee in 2025 describes a coupe, not the 2014 record convertible. The listing gives a 426/425 HP V-8, a four-speed manual, and a $495,000 result. It also describes the car as one of 59 1971 Hemi ’Cudas built with a four-speed and provides claims about its drivetrain, Track Pak, and documentation. Those are listing details for a different car, not attributes or a price for the Seattle convertible. View Mecum’s listing.

Mecum’s description calls the 2014 result the highest price ever paid for a 1971 Hemi ’Cuda convertible at public auction and promotes it as the world’s most expensive Mopar. Those are Mecum’s characterizations of the sale. The independent contemporary report supports the $3.5 million winning-bid figure, while the available sources do not settle a universal ranking of every HEMI-powered car auctioned worldwide or a uniform price calculation.
