Elva Roadster

• No coherent sold-price benchmark is available.

• Needs at least 3 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.

• Scarcity uses a conservative production base of approximately 149 vehicles.

• 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.

• SCI is indicative: the collector score clears the coverage gate, while Verified publication still requires the independent market-evidence gates.
