GT/RS track and limited models (GT3, GT4, RS, Spyder RS and similar, read from the listing title) are 64% of recent USD sales and sell for far more, so the overall median above leans toward them. For a typical 718 Cayman, the "excl. GT/RS" median is the better guide.
*Fair price range = middle 50% (25th–75th percentile) of USD sold prices in this sample. Condition, mileage, trim and options move any one car outside it.
Snapshot window: last 12 months. 116 sold cars (101 in USD), model years 2016–2025, sold Nov 3, 2025 to Oct 23, 2026. Non-USD sales are shown in their original currency and left out of USD statistics (we don't convert currencies).

Why: the median moved less than 8%.
Mix-adjusted median +3% vs the prior 3 months on 27 recent and 24 earlier USD online-auction sales (80% range -4% to +7%). Adjusted for trim and model year so a run of pricier cars doesn't look like a rising market.
Raw median $113,000 in the last 3 months vs $115,500 before (-2%; median model year 2023 → 2022).
12-month trend: +6% per year (mix-adjusted, 90 sales).
Sales volume (all auctions the data provider tracks for this model, Aug 2026 to Oct 2026): 9 sales vs 16 in the 3 months before (-44%). Context only; volume doesn't set the rating.
Red: monthly median USD sold price at online auctions in our sample (months with 3+ sales; bigger dot = more sales). Dashed line: 12-month mix-adjusted trend. Shaded: the two 3-month windows compared.
Based on a sample of public auction results for the Porsche 718 Cayman, not all sales. A rough read of recent price direction, not financial or investment advice and not an appraisal. How the market signal works.
