Mecum Auctions hammered down a 1970 Plymouth Hemi Cuda Convertible for $1.32 million at Kissimmee in January 2020. That barn-find survivor, unrestored with 15,000 miles, drew gasps. Three years later, another crossed the block at Barrett-Jackson Scottsdale for $825,000. Prices fluctuate. Yet both cars share Hemi DNA from Chrysler's wild 1969-1971 muscle sprint.
Factory Rarities: 14 Cudas, Thousands of Challengers
Plymouth built exactly 14 Hemi Cuda Convertibles in 1970. Fourteen. That's the tally from Galen Govier's Mopar registry, cross-checked against Chrysler records. Punch out a VIN like BS23R0A something, and you're in unicorn territory. Production ended abruptly; the Hemi's 426 cubic inches guzzled fuel amid rising insurance woes. Dodge fared differently. The 1971 Challenger R/T Hemi numbered 78 coupes and 23 convertibles. Total hardtops with the elephant motor: 1,116 across 1970-1971. Not rare, exactly. But drag-strip provenance lifts survivors.
Buyers chase numbers. Cuda scarcity commands 5x to 10x Challenger multiples. A clean '71 R/T Hemi coupe fetched $220,000 at Mecum Indianapolis in May 2023. Solid, not concours. Rarity tilts the scale.
Drag Strip Legacies Fuel Bidding Wars
Quarter-mile times hooked the first owners. The Hemi Cuda Convertible blasted 13.1 seconds at 107 mph stock, per Car Life tests from 1970. Heavy top-down body shaved acceleration versus coupes. Still ferocious. Dodge tuned the Challenger for straight-line fury. A 1971 R/T Hemi hit 13.3 seconds at 105 mph, Hot Rod magazine clocked. Similar. Both devoured Super Bee 440s and Chevelle SS 454s.
NHRA Super Stock classes crowned them kings. Grumpy Jenkins wrung 11-second passes from stock-looking Cudas. Ditto for Challenger pilots like Dick Landy. Race history prints money today. A '70 Hemi Cuda with Super Stock sheetmetal sold for $1.1 million at Mecum Kissimmee 2022. Proven '71 Challenger drag cars top $400,000. Pedigree pays.
Value Comparison
The purple line tracks the 1970 Plymouth Hemi Cuda Convertible's climb from $50,000 medians in 2005 to $1 million peaks by 2023. Cyan traces the 1971 Dodge Challenger R/T Hemi, steady from $80,000 to $300,000. Cuda surges ahead post-2015.
Auction Hammers: $1.3M Highs Meet $250K Medians
Barrett-Jackson Scottsdale 2014 saw a rotisserie '70 Hemi Cuda Convertible bid to $1.375 million, no reserve. Buyer's premium pushed it higher. Fast forward to Mecum's 2023 Monterey sale: $550,000 for a driver-quality example. Volatility bites. Challengers hold steadier. Mecum's Kissimmee January 2024 logged a '71 R/T Hemi at $275,000. Another at Worldwide Auctioneers Auburn 2023: $240,500.
Hagerty data pins Cuda Convertible medians at $950,000 for #1 condition in 2024. Challengers? #1 R/T Hemis hover at $285,000. Ten-year appreciation favors the Plymouth: 450% versus 220% for Dodge. Fuel prices tanked both new car sales in '71; survivors compound quietly.
Condition Kings: Rust Buckets to Nut-and-Bolt Restos
Rust ravaged Sunbelt strays. A '70 Cuda Convertible from Arizona, documented dry, doubled to $900,000 at RM Sotheby's 2019. Challengers suffer less; E-body unibody sheds water better. But rot still slashes values 50%. A rusty '71 R/T Hemi coupe limped to $120,000 at Mecum 2022.
Restoration costs skew ROI. Cuda glass and top mechanisms run $50,000 alone. Challenger parts flow cheaper via Modern Driveline reproductions. Investors eye originals. Numbers-matching Hemis add 30% premiums. Verify via Galen's list; fakes abound.
Investor Verdict: Bet Rarity or Volume?
CUDA. Scarcity wins long-term. With under 10 documented survivors, supply dries up. A fresh divorce sale could spike one to $2 million. Challengers multiply at auctions; 50+ cross blocks yearly. Steady 8-10% annual returns suit conservative portfolios.
Risks lurk. Emissions crackdowns crushed Hemi output; future bans unlikely. Electric conversions loom as threats. Park them dry. Polish brass. The Cuda Convertible's edge sharpens: 14 units mean every barn find rewrites markets. Challengers grind reliable gains. Pick your poison.
