The Holy Grail of Barn Finds: One-Owner Convertibles With Original Everything
In the classic car world, few discoveries generate more excitement than a genuine one-owner barn find. When that vehicle happens to be a 1966 Plymouth Sport Fury convertible – one of fewer than 3,500 produced – with rare factory options intact, the find transcends typical barn discoveries to become something truly special.
The 1966 Plymouth Fury represented the pinnacle of Chrysler’s full-size engineering, combining distinctive styling, solid construction, and genuine performance capability. The Plymouth Fury sold like hotcakes in 1966, but only about 40,000 were ordered in Sport trim. Of these, fewer than 3,500 were convertibles. This extreme rarity makes every surviving Sport Fury convertible significant, particularly examples with single-owner provenance and rare factory equipment.
For collectors seeking alternatives to overpriced muscle cars and ubiquitous Camaros, the 1966 Sport Fury convertible offers genuine rarity, full-size luxury, and surprising performance potential at remarkably accessible prices. The question isn’t whether these cars deserve preservation – it’s whether today’s enthusiasts can recognize their significance before the remaining examples disappear forever.
Understanding the 1966 Plymouth Fury Hierarchy
Plymouth offered its full-size Fury in five distinct trim levels during 1966, each targeting different market segments and buyer preferences. Understanding this hierarchy helps collectors identify the most desirable combinations and appreciate the Sport Fury’s unique positioning.
The Fury Lineup: From Basic to Luxury
Plymouth produced 687,514 automobiles in 1966. Plymouth produced 146,547 examples of the Fury III in 1966. This substantial production volume created multiple market tiers:
Fury I: Entry-level full-size Plymouth with minimal trim and equipment Fury II: Mid-range offering with additional chrome and comfort features Fury III: Volume seller with comprehensive standard equipment and luxury touches Sport Fury: Performance-oriented model with distinctive styling and upgraded mechanicals VIP: From 1966 until 1969, a luxury version of the Fury called the “Plymouth VIP” (marketed as the “very important Plymouth” in 1966) was fielded, in response to the Ford LTD, Chevrolet Caprice, and the AMC Ambassador DPL.
This tiered approach allowed Plymouth to compete across the entire full-size market, from fleet sales to luxury buyers seeking premium appointments without Mercury or Chrysler pricing.
Sport Fury: The Performance Full-Size
The Sport Fury occupied a unique niche in Plymouth’s lineup – a full-size car with genuine performance credentials. Unlike the mainstream Fury III, which prioritized comfort and space, the Sport Fury featured:
Performance Enhancements:
- Standard V8 power: No six-cylinder option – V8 engines only
- Upgraded suspension: Stiffer springs and shocks for improved handling
- Performance axle ratios: Better gearing for acceleration
- Heavy-duty cooling: Larger radiators and upgraded fans
- Dual exhaust system: Distinctive sound and improved breathing
Distinctive Styling:
- Unique trim: Special emblems, badging, and side moldings
- Bucket seats: Standard equipment unlike bench-seat Fury III
- Console shifter: Center console with floor-mounted transmission
- Sport instrumentation: Complete gauge package with tachometer
- Two-tone interiors: Distinctive color combinations unavailable on lesser models
Engine Options: From Practical to Powerful
The 1966 Plymouth Sport Fury offered a comprehensive engine lineup designed to meet diverse performance and budget requirements. The mill is a 318-cubic-inch (5.2-liter) small-block V8, which came standard in the Sport Fury in 1966. The 230-horsepower engine mates with a three-speed automatic gearbox, so the drivetrain combo is nothing to write home about.

- 340 lb-ft torque: Smooth, flexible power delivery
- Two-barrel carburetor: Simple, reliable fuel delivery
- Proven durability: Thousands of examples still running decades later
- Parts availability: Excellent support from aftermarket suppliers
The 383 V8: Balanced Performance

The 440 and 426 Hemi: Maximum Performance
For buyers demanding ultimate performance, Plymouth offered both the 440 cubic inch RB big-block and the legendary 426 Hemi. According to Plymouth’s production records, only 499 Furys were equipped with the 426 Hemi engine in 1966, making it one of the rarest and most desirable variants of the model.
440 Big-Block:
- 365 horsepower: Substantial power for full-size applications

The Bottom Line: Preservation Priority
The 1966 Plymouth Sport Fury convertible represents one of American automotive history’s most overlooked treasures. With fewer than 3,500 convertibles produced from the Sport Fury’s 40,000-unit production run, every surviving example deserves preservation consideration.
The discovery of a one-owner barn find with rare factory features elevates significance even further. These cars represent authentic, unmolested examples that have survived decades without modification or restoration attempts. Their originality provides valuable documentation of factory specifications and period equipment that benefits the entire collector car community.
From a financial perspective, restoration economics can work for Sport Fury convertibles, particularly examples with desirable options like air conditioning, four-speed transmissions, or big-block engines. Current market values ranging from $12,900 to $40,995 demonstrate healthy collector interest, while project car prices of $3,500-$5,000 create reasonable entry points.
However, the true value of preserving these cars transcends financial calculations. The 1966 Sport Fury convertible represents American automotive engineering at its peak – before safety regulations, emissions requirements, and fuel economy standards compromised design freedom. These cars embody a moment when manufacturers could build full-size convertibles with genuine performance credentials, luxury appointments, and distinctive styling.
For collectors seeking alternatives to overpriced muscle cars and ubiquitous Camaros, the Sport Fury convertible offers:
- Genuine rarity: Fewer than 3,500 examples produced
- One-owner authenticity: Original, unmolested specifications
- Rare factory options: Equipment combinations uncommon when new
- Investment potential: Undervalued compared to mainstream classics
- Preservation priority: Historical significance demands protection
The question isn’t whether a one-owner 1966 Plymouth Sport Fury convertible barn find is worth saving – it absolutely is. The real question is whether today’s collectors possess sufficient vision to recognize these cars’ significance before the remaining examples disappear into collections, succumb to neglect, or get parted out for restoration projects.
Every preserved Sport Fury convertible represents a victory for automotive history, ensuring that future generations can experience and appreciate one of the full-size era’s most distinctive and capable automobiles. Whether equipped with rare factory air conditioning, a four-speed manual transmission, or simply honest 318 power, each survivor deserves the preservation effort required to keep it on the road for decades to come.
