Action summary

Rising market posture

Base case points higher over the next 12 months. The strongest examples should lead the range upward, while cars needing history clarification or service work should lag closer to the current band.

Forecast reasoning

Evidence and risks

Current value leans on 8 completed sales from the last 6 months with high evidence confidence. observed dated-sale momentum is +2.8% annualized, supply is 0.08 listings per recent sale. The 12-month base case points higher at +6.7% after supply, confidence and mean-reversion checks.

Risks to the forecast

Thin public sales records can make short-term values look more volatile than the real buyer market.
High-mileage, modified or unclear-history cars trade at a discount and can distort simple averages.
Macro pressure, financing conditions and seasonal listing volume can soften transaction ranges.

Stored forecast reasoning

For reference, this is the stored long-run thesis; the chart above is currently evidence-backed and may differ: The 996 GT3 is increasingly recognized as the most affordable entry into aircooled-adjacent GT3 ownership, and that recognition keeps pulling buyers down-market from later cars.
