PRICE TRENDS & APPRECIATION
The quarterly trends indicate a generally stable market with some fluctuations in pricing. For instance, in 2026-Q2, the average price rose to $143,221 with a median of $141,209, reflecting a positive trend. Comparatively, the median price in 2025-Q4 was $129,998, indicating a recovery in prices over the past quarters. The overall trend suggests that while there are seasonal fluctuations, the market is appreciating modestly.
Auction Market Dynamics
The sell-through rate stands at 76%, indicating a relatively healthy auction market. The median price for sold vehicles is $122,000, while the median high bid is $108,000. This gap suggests that sellers may have unrealistic expectations, as buyers are willing to pay significantly less than the last asking prices. The ratio of sold to unsold vehicles indicates that while there is demand, sellers need to adjust their expectations to align with market realities.
Configuration Value Guide
The body style breakdown shows that the Cabriolet configuration commands a premium, with an average price of $141,156 and a median of $149,899. In contrast, the Coupe averages $135,102 with a median of $130,382. The 2016 and 2018 models are particularly valuable, with average prices of $151,258 and $152,299, respectively. This suggests that buyers are willing to pay more for these configurations and model years.
Mileage Impact
Mileage significantly impacts pricing. Vehicles with under 50,000 miles average $146,711, while those with 50,000 to 100,000 miles average $113,759. Vehicles over 100,000 miles command only $41,748 on average. This indicates that buyers are willing to pay a premium of approximately $32,952 for low-mileage vehicles, highlighting the importance of mileage in valuation.
Regional Pricing
Geographic distribution reveals that vehicles in the Northeast command the highest average price at $176,078, while those in the South average $135,767. The West region has a competitive average of $140,011. This suggests potential arbitrage opportunities for buyers in regions with lower average prices, such as the South.
Market Health Indicators
The average days on market is 65, with a median of 35 days, indicating that listings are selling relatively quickly. However, the presence of 50 listings with price reductions suggests that some sellers may be adjusting their expectations due to soft demand for certain vehicles. The introduction of 24 new listings this week indicates a steady supply in the market.
Investment Outlook
Given the stable trend direction and the modest appreciation observed in recent quarters, the Porsche 911 GTS (991) appears to be a stable investment. While not experiencing rapid appreciation, the market is resilient, suggesting that it may be a good hold for collectors and enthusiasts.
Buying Recommendations
For potential buyers, focusing on the 2016 and 2018 models is advisable, as they command higher prices and are more desirable. Targeting vehicles with under 50,000 miles will also yield better value, as these typically command a premium. Buyers should be cautious of listings with high asking prices relative to recent auction outcomes, as this indicates a reserve gap and may lead to unsuccessful bids.
