PRICE TRENDS & APPRECIATION
The market for the Cayman GT4 has demonstrated a consistent appreciation trend over recent quarters. For instance, in 2026-Q2, the median price reached $199,900, reflecting a significant increase from previous quarters. The average price in 2025-Q4 was $171,981, while the median price in 2025-Q3 was $186,475. This upward trajectory indicates strong demand, particularly for models from 2023 and 2024, which are the most common years sold.
Auction Market Dynamics
The sell-through rate stands at 75.9%, indicating a healthy auction market. The median price for sold vehicles is $133,000, while the median high bid is $147,250, suggesting a reserve gap where sellers may have unrealistic expectations. The ratio of sold to unsold/high_bid indicates that while buyers are willing to pay a premium, sellers may need to adjust their expectations to facilitate sales.
Configuration Value Guide
The body style breakdown indicates that the Coupe configuration is the most common, with an average price of $170,404 and a median price of $149,520. The price by year data shows that the 2024 model commands the highest average price at $222,853, followed closely by the 2025 model at $211,232. This suggests that newer models are highly valued in the market.
Mileage Impact
Mileage significantly impacts pricing, with vehicles under 50,000 miles averaging $170,933, while those in the 50,000-100,000 mile range average only $94,397. This indicates that buyers are willing to pay a premium for lower mileage vehicles, with a notable price difference of approximately $76,536 between the two mileage brackets.
Regional Pricing
Geographic distribution shows that the Midwest has the highest average price at $216,458, while the South has the lowest at $145,900. This suggests potential arbitrage opportunities for buyers in lower-priced regions, particularly in the South, where prices are significantly lower compared to other regions.
Market Health Indicators
With an average of 80 days on the market and 19 new listings this week, the market appears to be stable. However, the presence of 20 listings with price reductions suggests that some sellers may be adjusting their expectations in response to market conditions. The healthy sell-through rate of 75.9% further indicates that demand remains strong.
Investment Outlook
Given the appreciating trend and strong demand for newer models, the Cayman GT4 appears to be a sound investment. The consistent price increases and healthy auction dynamics suggest that this asset class will continue to appreciate, making it a favorable option for potential buyers.
Buying Recommendations
For prospective buyers, targeting the 2024 and 2025 models may yield the best value, as these years command higher prices but also reflect the strongest demand. Buyers should consider vehicles with mileage under 50,000 to maximize value, as these typically command a significant premium. Additionally, engaging in auctions with a realistic bidding strategy, particularly in light of the observed reserve gap, will be crucial for securing favorable deals.
