PRICE TRENDS & APPRECIATION
The quarterly trends indicate a declining market, particularly notable in the first half of 2026, where the median price dropped to $139,450 in Q1 and $165,250 in Q2. This is a stark contrast to Q4 2025, where the median price was $182,000. The overall trend suggests that while there was some stability in 2025, the beginning of 2026 has seen a significant drop in prices, indicating a potential shift in buyer sentiment.
Auction Market Dynamics
The auction outcomes reveal a sell-through rate of 76.4%, indicating a relatively healthy market. However, the median price for sold vehicles at $134,000 is significantly lower than the median high bid of $150,000, suggesting a reserve gap where sellers may have unrealistic expectations. The high number of unsold vehicles (2) and pending sales (4) further indicates that while there is interest, buyers are not willing to meet sellers' asking prices.
Configuration Value Guide
The body style breakdown shows that Coupes are more prevalent, with an average price of $167,324 and a median price of $189,850. In contrast, the Spyder configuration has only one listing at a significantly lower price of $2,988, which may not be representative of market value. The price by year data indicates that models from 2024 and 2025 command the highest prices, averaging $211,454 and $217,652 respectively, suggesting these years are currently the most desirable.
Mileage Impact
Mileage analysis indicates that vehicles with under 50,000 miles average $177,161, while those with 50,000 to 100,000 miles average $139,278. This reflects a premium of approximately $37,883 for low-mileage vehicles, highlighting the importance of mileage in determining value.
Regional Pricing
The geographic distribution data shows that the "Unknown" region has the highest average price at $187,649, while the Midwest has the lowest at $219,100. This suggests potential arbitrage opportunities for buyers in the Midwest, where prices are comparatively lower.
Market Health Indicators
The average days on market is 91, with 30 new listings this week and 41 listings experiencing price reductions. This indicates a softening demand, as many sellers are adjusting prices to attract buyers. The relatively stable number of new listings suggests that supply is keeping pace with demand, but the price reductions indicate that sellers may need to recalibrate their expectations.
Investment Outlook
Given the current trend direction of depreciation and the recent quarterly trends, the outlook for the Porsche 718 Boxster/Cayman GT4 appears to be cautious. While the asset class is not appreciating at this time, potential buyers may find opportunities in the 2024 and 2025 models as the market stabilizes.
Buying Recommendations
For buyers, focusing on 2024 and 2025 models may yield the best value, particularly those with lower mileage. Target price ranges should be set around the median asking price of $190,346, but buyers should be prepared to negotiate downwards given the current market dynamics. It is advisable to avoid listings with high asking prices relative to recent sales data, particularly those that have been on the market for extended periods.
