Factor breakdown
Open any factor to see what it means and which evidence supports it.
Collector quality and evidence are separate. Structural collector factors carry 75%; observable market factors carry 25%.
Methodology & score historyPublication gates
• No coherent sold-price benchmark is available.
• Needs at least 5 comparable sold observations inside the 36-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
• 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 4 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.

Price evidence
Launch MSRP, realized sales, public asking inventory, valuation guides and reported one-off commission estimates stay separate. Auction venue, mileage, model year and specification context are exposed where sources publish them. Source currencies are preserved and estimates are never relabelled as MSRP, transactions or current market value.
Manufacturer / launch MSRP
Original published launch pricing. Net/gross basis is preserved where the source states it.

Count not published
Porsche official 991.2 GT2 RS launch material confirms the series but does not publish a global fixed production total. No third-party regional registration/VIN count is promoted to a worldwide production figure. Research is complete for the count field; scarcity remains unscored until an authoritative global total is available.
