To estimate the price of the 2013 Peugeot 508 I4 1.6L GT Line (Top) with 283000 km mileage, I considered the following data points: The new price of the 2025 Peugeot 508 1.6T GT Line is SAR 170200. Assuming a 10% depreciation per year, the 2013 model would have depreciated by approximately 90%, giving a rough estimate of SAR 17020. However, the GT Line is a higher trim than the Allure, which affects the price. An offer was accepted for a 2013 Peugeot 508 I4 1.6L Allure (Base) with 186500 km for SAR 19000 in December 2023. Given the higher mileage and the higher trim of the car in question, I adjusted the price downwards. Listed prices for similar Allure variants range from SAR 24000 to SAR 30000, but these are likely higher than actual selling prices. Considering all these factors, I estimated the market price accordingly.
