Conclusion and outlook
Summary of findings
Analysing Porsche 911 GTS price development from 2010 to 2026 shows clear patterns and supports the following conclusions:
The four core findings
- The influence of configuration: the combination of body style, drivetrain and above all gearbox has a significant influence on market value. In 2026 the manual premium depends heavily on the cell: +€27,500 in the 997.2 Cabriolet and +€9,900 in the 997.2 C4, +€28,000 in the small 991.1 pool, +€13,000 on the 991.2; on the 992.1 manuals actually trade below PDK.
- Differences between generations: the older generations (997.2, 991.1) have a substantial part of their depreciation behind them and show signs of stability or even appreciation. The newer cars (991.2, 992.1) are still in the typical new-car depreciation cycle, though on the 991.2 a stabilisation has been emerging since 2024.
- Particularly strong value retention: the 997.2 GTS with the manual gearbox in particular shows remarkable stability and has gained value again after a trough. As the first GTS generation and the last GTS with hydraulic power steering, it enjoys a special status among collectors.
- The value of rarity: the rarer a given combination of model, body style, drivetrain and gearbox, the better it generally holds its value. Manual gearboxes in particular are becoming an important factor in long-term value development.
Looking ahead
- The 997.2 GTS with the manual gearbox should continue to gain value, since as the first GTS generation and the last GTS with hydraulic power steering it holds a special place in Porsche history.
- The 991.1 GTS, as the last naturally aspirated GTS, may have passed its price low in the coming years and gain value again, particularly in manual form.
- The 991.2 GTS has been stabilising since 2024 and the 2026 median sale prices already sit above the 2025 averages; a pronounced appreciation phase, however, is probably still some years away.
- The 992.1 GTS will follow the typical new-car depreciation pattern, though special editions should hold their value better; for manuals, no premium can yet be demonstrated in the 2026 median sale prices.
Appreciation potential: the 911Finder assessment
From an investment point of view, the 997.2 GTS with the manual gearbox and the 991.1 GTS with the manual gearbox look particularly interesting. The 997.2 GTS is already in an appreciation phase, while the 991.1 GTS may be at or just past the low point of its value curve and therefore offers potential for future gains. The common denominator for good value retention comes down to a manual gearbox, low mileage and unbroken documentation as the key factors.
Buying advice by budget: which GTS fits yours?
Budget ranges based on the June 2026 median sale prices from the MarqueScope SOLD archive (Coupé and Cabriolet; rear- and all-wheel-drive variants sit close together in each generation): 997.2 GTS €95,000-103,000, 991.1 GTS €115,991-120,946, 991.2 GTS €123,000-132,991, 992.1 GTS €155,000-169,000, 992.2 GTS €181,100-204,900. Targa variants trade roughly €13,000 to €29,000 above the corresponding all-wheel-drive Coupé in each generation (992.2 GTS Targa: €215,976).
