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 30 vehicles.
• Listing-supply coverage is not yet sufficient, so Supply Dynamics remains unscored and Data Confidence is capped.
• Collector Evidence G contributes source-backed structural evidence from 2 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.

Full narrative, value drivers and risk factors
The 30-car cap and verified homologated-production-car Laguna Seca record are the strongest objective collector anchors currently available.
Potential value drivers
- • Koenigsegg limits Sadair’s Spear to 30 cars.
- • Strict 30-car road-legal production series.
- • A later road-legal, track-focused Koenigsegg positioned beyond the Jesko Attack’s Laguna Seca benchmark
- • it subsequently set a quicker homologated-production-car lap there.
- • Factory specification includes 1,625 hp on E85, 1,385 kg curb weight, revised cooling, lighter track-focused interior and a paddle-only Light Speed Transmission calibration.
- • Sadair’s Spear superseded Koenigsegg’s earlier Jesko Laguna Seca production-car benchmark in 2025.
