To estimate the price of the 2018 Porsche 911 Carrera 4 GTS GT3 Standard, I started by looking at the new car price for the 2025 Porsche 911 Carrera 4 GTS, which is AED 635400. Applying a 10% annual depreciation over 6 years (2018 to 2024), the estimated value is AED 317700. I also considered the selling price of a 2017 Porsche 911 Carrera 4 GTS with similar specs, which sold for AED 369750 in May 2024. Adjusting for the additional year of depreciation, the estimated value is AED 332775. The listed price of a similar 2017 model is AED 435000, but this is likely higher than the actual selling price. Combining these data points, I estimate the market price to be around AED 325000.
