How SCI works
Collector quality and evidence are separate. Structural collector factors carry 75%; observable market factors carry 25%.
Methodology & score historyResearch notes
Publication gates
• No coherent sold-price benchmark is available.
• Needs at least 2 comparable sold observations inside the 120-month market window.
• Needs at least two independent source providers in the benchmark window.
• Needs at least two comparable sales in the last 24 months.
Rationale
• Scarcity uses a conservative production base of approximately 75 vehicles.
• Source-backed current-market evidence sits +42908.4% versus the researched launch MSRP in the same currency.
• Collector Evidence G contributes source-backed structural evidence from 3 independent sources; it does not substitute for transaction evidence.
• SCI 1.5 separates structural collectibility from evidence confidence: scarcity, collector significance and future relevance carry 75% of SCI; observable market factors carry 25%. Thin public-market evidence primarily reduces Confidence rather than intrinsic collector quality.
• Uncovered factors retain conservative neutral priors in the score model while their missing support remains visible in factor coverage and Evidence Confidence; they are never presented as equally evidenced facts.
• SCI is indicative: the collector score clears the coverage gate, while Verified publication still requires the independent market-evidence gates.

Collector research notes
Full narrative, value drivers and risk factors
RM Sotheby’s sold an original factory-bodied, matching-numbers DB4 GT with original alloy panels for £2,408,000 in 2016, demonstrating top-tier collector demand for correctly authenticated examples.
Potential value drivers
- • Aston Martin sources use two definitions: the historic DB4 GT page says 94 units total, while Aston Martin’s continuation/history material and RM Sotheby’s identify 75 factory/Touring-bodied DB4 GTs. The CSV’s 75 figure is valid only for the factory/Touring-bodied definition.
- • Low-volume competition-oriented DB4 derivative. For factory/Touring-bodied cars, 75 original examples are documented
- • broader DB4 GT accounting can reach 94 depending on inclusion of other coachwork/specials.
- • Competition-focused flagship derivative of the DB4, developed for GT-class racing and sitting above the standard road DB4 in performance intent.
- • Shortened DB4 platform, approximately 185 lb lighter, magnesium-panelled Superleggera body, twin-plug 3.7-litre six with triple carburettors and 302 bhp.
- • Purpose-built “gentleman’s racer” directly linked to period GT competition and Stirling Moss’s prototype victory
- • a key road/race bridge in Aston Martin history.
Risk factors
- • Extremely high: original chassis/engine, factory body, alloy panels, period race history, damage history and continuous ownership file are material. Continuation cars must be excluded from original-car comparisons. · Definition/authenticity risk is substantial: original Touring-bodied cars, Zagato/specials and later continuation cars can be confused · period competition use also makes repair/panel originality critical.
