Porsche Cayman GT4

The Porsche Cayman GT4 has appreciated 21.4 percent over the past 12 months, with the US median now sitting at $111,991, a strong move that signals sustained collector interest in this generation of the model.

Recent transaction activity has tracked 12 sales in the 12-month period across a broader dataset of 17 total sales, suggesting moderate liquidity in the secondary market. The sample size is workable for establishing trend direction, though the moderate liquidity profile means buyers and sellers should expect somewhat deliberate matching rather than rapid execution.

The Cayman GT4 carries a collectible classification with a score of 5, reflecting its appeal as a stable modern classic. Desirability remains moderate, which is consistent with the car's positioning as a sub-911 model with strong enthusiast credentials but not the brand prestige of higher-tier variants.

Average mileage on transacted examples sits at 16,050 miles, indicating these cars are being driven and preserved rather than locked away, a healthy sign for a driver-focused sports car expected to see light use.

The base case projection holds the median flat at $111,991 through both the three-year and five-year horizons, meaning the market is pricing in stability rather than continued appreciation after this year's 21.4 percent climb. This signal aligns with the HOLD recommendation and reflects a market that has already priced in much of the near-term collector appetite for this generation.
