Forecast reasoning

Evidence and risks

Current value leans on 17 completed sales from the last 6 months with high evidence confidence. observed dated-sale momentum is +4.0% annualized, supply is 0.09 listings per recent sale. The 12-month base case points higher at +7.3% 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: 991-generation GT3 supply has matured into the market in meaningful volume, which has slowed the pace of appreciation seen in earlier years.
