8 factors
How SCI works

Collector quality and evidence are separate. Structural collector factors carry 75%; observable market factors carry 25%.

Methodology & score history
Research notes

Publication gates

• Needs at least two independent source providers in the benchmark window.

• Needs at least two comparable sales in the last 24 months.

Rationale

• 3 comparable USD sales underpin the current 72-month benchmark.

• Observed benchmark CAGR is +8.3% across the longest suitable 2–6 year comparison window.

• Recent transaction momentum versus the preceding period is +27%.

• Scarcity uses a conservative production base of approximately 1,948 vehicles.

• Collector Evidence G contributes source-backed structural evidence from 6 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.

Collector intelligence

Why it matters.

The collector case in a few signals first. Full editorial notes and source detail remain available below.

Rarity

Finite 1,948-car production, final-991 status and GT-derived manual powertrain create a clearly defined special-series identity

Significance

RM has documented completed auction/private sales.

Heritage

Final special 991 derivative combining Speedster heritage with GT3/911 R-based performance technology.

Technology

Combines a high-revving naturally aspirated GT3-derived flat-six with a six-speed manual and lightweight GT chassis/body technology.

Collector research notes

Full narrative, value drivers and risk factors

Finite 1,948-car production, final-991 status and GT-derived manual powertrain create a clearly defined special-series identity; RM has documented completed auction/private sales.

Potential value drivers

  • • Porsche limited 991-generation 911 Speedster production to 1,948 units.
  • • Explicit 1,948-unit limited special series, the number referencing Porsche's founding year.
  • • Final special 991 derivative combining Speedster heritage with GT3/911 R-based performance technology.
  • • Combines a high-revving naturally aspirated GT3-derived flat-six with a six-speed manual and lightweight GT chassis/body technology.
  • • Closed the 991 production era while connecting the 1954 Speedster body concept to Porsche's modern GT programme.

Risk factors

  • • High: serial number within 1,948, original factory options (including Heritage Design), mileage, service history and matching accompanying items are explicitly catalogued. · Do not treat Heritage Design and non-Heritage cars as identical comparables without option normalization. Verify series number, original body/specification, mileage and accident/paint history.
