Giannini 500 Classic Cars: Prices & Market Values
The market value of Giannini 500 classic cars is primarily determined by technical condition, originality and mileage, as well as rarity, history and documentation. A well-maintained, largely original vehicle with low, verifiable mileage and complete history including appraisals and documentation typically achieves significantly higher prices than a comparable vehicle with deferred maintenance, many modifications or unclear provenance.
Giannini 500: Market Prices & Value Trends
Based on Classic Trader marketplace sales data from February 2021 to December 2025, the Giannini 500 (including Giannini Fiat 500 TV/TV L/TV R/TV S, 590 GT and 650 NP) shows a broadly stable to slightly firming market, with most recent asking prices clustering in the mid-teens. While individual adverts range from about £4,300 to £27,700, these extremes are best treated as condition- or spec-driven outliers rather than the “going rate”. In practical terms, a realistic market window today is typically around £9,000–£19,000, with well-presented Giannini Fiat 500 TV models from the mid-1960s (notably 1966–1969) often sitting in the £12,000–£16,500 band. The sportier 590 GT and the 650 NP can command a premium when correctly documented, but pricing still depends heavily on originality, known upgrades, and restoration quality. Most data points come from Italy, with additional activity in Germany, France and the Netherlands, suggesting demand is strongest in mainland Europe and focused on authentic, well-sorted cars.
History of the Giannini 500
The Giannini 500 is rooted in the longstanding tradition of Italian engineering excellence, leveraging the classic Fiat 500’s chassis with Giannini’s performance upgrades. Giannini began modifying these cars to extract greater dynamism from the popular city car, focusing on engine enhancements, improved handling, and personalised aesthetics. Over time, the Giannini 500 evolved into a platform for distinctive models like the 500 TV (Turismo Veloce), 500 TVL, 500 TVS, and 650 NP—each bearing the hallmark of handcrafted Italian automotive culture.
Model History
Giannini’s range on the 500 base includes the TV, TVL, and TVS variants—each progressively more performance-oriented. The TV stands for 'Turismo Veloce', highlighting the focus on spirited driving. Engine options ranged from reworked 500cc power units up to 650cc, often with custom cylinder heads and upgraded internals. Transmission options occasionally featured synchronised gearboxes, and select cars sported the renowned 8-bolt body. All models prioritised period authenticity, typically retaining original mechanicals and Giannini-specific badges and documentation.
Highlights and Standout Features
A Giannini 500 is not simply a tuned Fiat but a comprehensive transformation: from upgraded suspension (often sport lowering kits) to specific Weber dual-barrel carburettors and typically Monza-style exhausts, everything points to performance and authenticity. OEM details like Carello headlights, Altissimo rear lights, original sports steering wheels (such as Momo wood-rimmed), dual-tone leatherette sports seats, and rare alloy wheels (Cromodora, Abarth) are frequent. Interiors often include restored or period-correct carpets and mats, as well as vintage-style audio enhanced with modern features (like Bluetooth). Extras such as original keys, logbooks, and number plates align with collector demand, while ASI certification underlines historical relevance.
Technical Data
Special Editions and Collectible Models
Special editions include the Giannini 500 TV, TVL, and TVS (Turismo Veloce Special)—each produced in limited numbers with unique tuning. The rare 650 NP stands out for its larger displacement and performance upgrades. Models with original ASI certification and matched period documentation are of particular interest to collectors. Carefully preserved specimens with factory-specific badges, original paint/trim, and performance parts (e.g., Cromodora wheels, Momo steering wheels, sport gear knobs) are highly sought after.
Engine and Performance, Transmission and Handling
A true departure from the basic Fiat 500, Giannini’s modifications elevate handling and acceleration considerably. Upgraded engines (often 650cc) deliver a taut, energetic drive, while tuned suspension setups enhance road holding. The inclusion of performance carbs and free-flow exhausts render the Giannini 500 both responsive and aurally distinctive. Period gearboxes vary, with synchronisation in some. Mechanical reliability hinges on authentic restoration—most parts, from carbs to ignition, are either original or period-correct replacements. Restoration often includes fresh suspension components, renewed brakes, and revised steering, strengthening the dynamic package. • 500 TV: Uprated 500cc, distinctive Giannini exterior badgework, tuned suspension • 500 TVL/TVS: More aggressive engine and cam profiles, Monza type exhausts • Giannini 650 NP: 650cc, enhanced torque and top speed, rare on the market
Interior, Comfort, Exterior and Design
Typical Giannini 500s feature carefully restored interiors—sports seats (typically leather or fine vinyl in striking two-tone colourways) and unique Giannini badges are standard. Wood or leather sports steering wheels (commonly Momo) and contrasting colour dashboards echo motorsport influences of the period. Folding roofs ('sunroof') add open-air driving charm. On the outside, period-livery, rare alloy wheels (Abarth, Cromodora), distinctive Giannini ornamentation, and restored lighting (Carello, Altissimo) provide authenticity. Accessories such as vintage radio replicas (Bluetooth-enabled), custom floor mats, and aluminium gear knobs round out the enthusiast package.
Other Relevant Information
For collectors, original number plates and documentation significantly increase authenticity and desirability. Many vehicles come equipped for international export, and administrative assistance in processing documentation is often provided. Vehicles are typically restored using only period-correct Giannini or OEM Fiat parts, never reproductions, ensuring accuracy for historical registration bodies such as ASI.
Summary
The Giannini 500 personifies the art of Italian small-car tuning—each model meticulously upgraded in both mechanics and design. With model variants like the TV, TVL, TVS, and rare 650 NP, the vehicles on offer provide a unique opportunity to experience authentic performance upgrades from Italy’s mid-century tuning scene. Collector documentation and attention to period authenticity set these apart from standard Fiat 500s, while 100% of classic Giannini supply and demand is focused on this model, underlining its unique presence in the UK enthusiast market.
