The muscle car hierarchy is usually defined by production numbers that range in the hundreds or thousands. Collectors lose their minds over the 14 Hemi ‘Cuda convertibles built in 1970, or the handful of Hemi Challengers that escaped the factory with a four-speed manual. But even those ultra-rare icons are mass-produced compared to the “White Whale” of the Mopar world. During the peak of the executive muscle era, one specific car was commissioned to bridge the gap between high-luxury cruising and the gritty world of professional drag racing. It was a vehicle that wasn’t supposed to exist outside of a marketing department’s imagination.
By 1970, the industry was shifting. The era of the stripped-out, bench-seat drag racer was being superseded by a demand for “Executive Muscle”: massive, high-luxury performance barges designed for the corporate elite who wanted 440-cubic-inch power without sacrificing air conditioning or power steering. This transition created some of the most overlooked gems in the Chrysler-Plymouth catalog.
However, one specific vehicle stands alone as a statistical anomaly. It is 21 times rarer than a Hemi ‘Cuda convertible and represents a unique collaboration between a major manufacturer and a legendary shifter company. For decades, it was considered a ghost, a promotional myth that most historians believed had been lost to the crusher.

The Ghost Identified: 1970 Chrysler 300 Hurst Convertible
The car in question is the 1970 Chrysler 300 Hurst Convertible. While the standard 300 Hurst coupe is a rare sight with approximately 501 units produced, this is the only factory-authorized convertible ever built. It was a Special Order (Code Q06993) designed specifically for promotional use by Hurst Performance. While the title of this article mentions Plymouth, this car represents the pinnacle of the broader Chrysler-Plymouth performance lineage, sharing the same Mopar architecture and Special Commando DNA that defined the Plymouth performance division during the late sixties.
Constructed as a promotional tool for the legendary Linda Vaughn, the “Miss Hurst Golden Shifter,” this car was never intended for a showroom floor. It was sent directly from the Chrysler assembly line to Hurst Performance Research in Warminster, Pennsylvania. The goal was to create a mobile billboard that could carry Vaughn and a massive replica of a Hurst shifter around NASCAR and USAC tracks.
Because it was a one-off promotional build, it lacked a standard MSRP and was never officially listed in a Chrysler catalog. This lack of a paper trail contributed to the car’s “ghost” status for nearly half a century. It was an engineering experiment dressed in Spinnaker White and Satin Gold, acting as the ultimate brand ambassador for the Hurst Corporation during the most competitive year in muscle car history.

The 300 Hurst Convertible Has Serious Performance Credentials
Under the massive fiberglass hood sat the heart of Chrysler’s big-block performance: the 440 TNT V8. While the Plymouth variants were labeled as the Super Commando, the Chrysler TNT-spec engine was specifically engineered for high-speed executive transit. It produced a formidable 375 hp and 480 lb-ft of torque.
Unlike the peaky delivery of the 426 Hemi, the 440 TNT provided a massive wave of low-end torque that was better suited for the 300 Hurst’s considerable mass. The engine featured a single four-barrel Carter AVS 4-barrel carburetor sat atop an iron intake manifold, with heavy-duty forged connecting rods and a high-lift camshaft designed to move the car’s 4,400-pound weight with deceptive ease.
The drivetrain was rounded out by a heavy-duty TorqueFlite 727 automatic transmission, which was the only gearbox in the Mopar arsenal capable of handling the 440’s torque within the C-body chassis. To ensure the car didn’t handle like a standard luxury barge, it was equipped with the heavy-duty suspension package from the Chrysler police pursuit vehicles. This included thicker torsion bars, heavy-duty leaf springs, and a front anti-roll bar.
This technical setup allowed the car to remain composed during high-speed parade laps on banked NASCAR tracks, where stability was a safety requirement rather than a luxury. The car sat on 15-inch styled road wheels wrapped in Goodyear Polyglas tires, a setup that was essential for putting 480 lb-ft of torque to the pavement without immediate tire disintegration.
The Special Linda Vaughn Connection
The 1970 300 Hurst Convertible was more than a performance car; it was a stage. It was designed specifically for Linda Vaughn, the “First Lady of Motorsports,” who was the face of Hurst Performance. During the 1970 race season, the car was a permanent fixture at major racing events, including the Daytona 500 and the Indianapolis 500.
The transformation from a luxury cruiser into a promotional icon required significant structural modifications. Hurst technicians replaced the standard steel hood and trunk lid with custom fiberglass units. The hood featured a functional, rear-facing air scoop, while the trunk lid integrated a massive “power-wing” spoiler that has since become one of the most polarizing design features in Mopar history.
The most striking technical detail was the custom-fabricated rear deck. Because the car was designed to carry Vaughn on the back during parade laps, Hurst reinforced the area behind the rear seats to support her weight at speeds up to 60 mph. They also installed a massive, non-functional Hurst shifter handle that emerged from the trunk area, standing nearly six feet tall. This visual stunt was meant to reinforce Hurst’s dominance in the aftermarket shifter market. The two-tone Spinnaker White and Satin Gold paint scheme was applied with a specific Hurst layout that differentiated it from any standard Chrysler 300. This car didn’t just attend races; it was the centerpiece of the pre-race spectacle, representing the peak of the “Shifter Girl” era of American motorsport marketing.
Why The Chrysler 300 Hurst Convertible Can’t Be Captured
The reason this car is impossible to capture is twofold: its physical rarity and its airtight provenance. After its promotional duties ended in the early 1970s, the car was sold into private hands, eventually landing in the collection of Hurst Vice President Jack Duffy. For a significant period, the car vanished from the public record. In the pre-internet era of car collecting, many assumed the car had been returned to its standard 300 form or, worse, scrapped after its fiberglass panels began to deteriorate. Because it was a one-of-one unit, there were no “sister cars” to track, making it one of the most challenging vehicles for historians to verify – a true ghost in the muscle car world.
The car eventually resurfaced in the late 20th century and underwent a meticulous restoration to its 1970 promotional specifications, including the re-installation of the parade-spec rear deck. Today, it resides in a private family collection and is almost never seen on the open market. Unlike a Hemi ‘Cuda or a Superbird, which occasionally cross the block at high-profile auctions, the 300 Hurst Convertible is a settled asset. It is a piece of corporate history that has reached its final destination. It isn’t just a car; it’s a non-transferable artifact of the Hurst legacy.
Even for the wealthiest collectors, this 1-of-1 Mopar is essentially a ghost that remains permanently out of reach.
The 300 Hurst Convertible’s Value And The Surprisingly Attainable Alternative
Assigning a hard value to a 1-of-1 vehicle with this level of historical weight is difficult, but we can look at its siblings for a baseline. As of early 2026, a 1970 Chrysler 300 Hurst Coupe in excellent to good condition carries an average market value between $45,000 and $65,000. Exceptional examples have crossed the $90,000 mark at high-profile events. Given the convertible’s uniqueness and its direct link to Linda Vaughn, it is estimated that the car would command a price upwards of $500,000 if it ever appeared at auction.
For buyers who want the 300 Hurst experience without the impossible barrier of a one-off convertible, the 1970 Chrysler 300 Hurst Coupe is the only viable entry point. With roughly 500 units built, it provides the same 440 TNT powertrain, the unique fiberglass hood and trunk, and the Spinnaker White/Satin Gold aesthetic. While still a rare “unicorn” in the Mopar world, these coupes appear on the market semi-regularly and represent one of the best values in the high-displacement executive muscle segment.

The Unicorn Registry: Ridiculously Rare Mopars
If you think the 300 Hurst Convertible is elusive, consider these other statistical anomalies in the Mopar ecosystem. These vehicles represent the peak of rarity and investment potential in the current 2026 market:
- 1971 Plymouth Hemi ‘Cuda Convertible: Only 12 were produced. In January 2026, a “Sno-White” example sold at auction for $3,300,000. These are widely considered the “Holy Grail” of muscle cars.
- 1970 Dodge Challenger R/T Hemi Convertible: Just nine units were built with the 426 Hemi. Current valuations for these cars hover between $1,500,000 and $2,000,000 depending on the transmission (the 4-speeds being the most coveted).
- 1969 Dodge Hemi Coronet R/T Convertible: An extreme rarity with only 10 built. Recent 2026 auction data shows these cars fetching approximately $770,000.
- 1969 Dodge Charger Daytona (Hemi): While 503 Daytonas were built to satisfy NASCAR rules, only about 70 featured the 426 Hemi. These now command between $1,500,000 and $3,500,000, with one Hemi Daytona selling for $3.3 million in 2024.
The Investment Value of the 1970 Chrysler 300 Hurst Convertible
The 1970 300 Hurst Convertible represents more than a statistical anomaly. It is a mechanical pivot point, marking the exact moment Chrysler realized they could sell high-displacement performance through the lens of executive luxury rather than raw, stripped-out aggression. While the 440 TNT V8 and the heavy-duty C-body architecture provided the necessary technical floor, the car’s true terminal value is dictated by its status as a rolling marketing artifact. As a one-of-one promotional build for Linda Vaughn and Hurst Performance Research, it transcends standard collector car metrics. It is a piece of documented corporate heritage that captured the final, extravagant peak of the original muscle era before fuel crises and emissions mandates prioritized pragmatism over Spinnaker White and Satin Gold pageantry.
In the current 2026 climate, the 300 Hurst series has matured into a reliable blue-chip asset for collectors looking to diversify beyond the oversaturated E-body market. While the January 2026 auction results for Hemi ‘Cuda convertibles ($3,300,000) establish the extreme ceiling of the Mopar world, the 300 Hurst series offers a more nuanced entry into high-tier collecting.
The standard 300 Hurst Coupe currently commands a Hagerty-verified value of $92,750 in concours condition, which is one of the most stable C-body valuations on the books. However, the Linda Vaughn Convertible remains the unreachable anchor of the lineage. At a $500,000+ museum-grade valuation, it serves as a permanent reminder that in the world of Mopar, true rarity is measured not just in cylinder count, but in the weight of a narrative that can never be replicated.
