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.
• Data Confidence must reach at least 68/100.
Rationale
• Scarcity uses a conservative production base of approximately 100 vehicles.
• Manufacturer/source research indicates the model allocation is sold out, which strengthens Supply Dynamics without pretending that illiquidity equals weak demand.
• 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 1.5 migration guard limits unsupported downward changes to 3 points and weak-intrinsic-coverage upward changes to 5 points during the September 2026 transition window. Evidence-backed halo sanity floors require all three structural factors to be covered.

Significance
allocation sell-out is not treated as a secondary sale.
Rarity
Gordon Murray Automotive announced the fixed-roof T.33 with a strict production limit of 100 cars.
Technology
Specially reconfigured Cosworth GMA V12 combined with a new carbon-fibre/aluminium superlight architecture and a two-seat road-car package.

A strict 100-car run and full allocation just over a week after launch provide defensible rarity and primary-demand evidence; allocation sell-out is not treated as a secondary sale.
Potential value drivers
- • Gordon Murray Automotive announced the fixed-roof T.33 with a strict production limit of 100 cars.
- • 100-car T.33 Coupe/base programme
- • all 100 allocations had deposits just over a week after launch. Later T.33 body derivatives are not merged into this row.
- • T.33 is GMA’s second all-new supercar and explicitly follows the company’s halo T.50 rather than replacing that halo position.
- • Specially reconfigured Cosworth GMA V12 combined with a new carbon-fibre/aluminium superlight architecture and a two-seat road-car package.
- • T.33 established GMA’s second production model line after the halo T.50 and broadened the company into a more compact two-seat supercar architecture.
Risk factors
- • Factory build/delivery documentation, original books/tools, specification and continuous GMA service history are material exact-car verification items.
- • Public secondary price discovery is not yet established
- • exact build/specification and factory documentation must be verified rather than using later T.33 derivatives as comparables.
