To estimate the price of the 2018 Peugeot 3008 GT Line I4 1.6L Turbocharged with 115972 km mileage, I first considered the selling price of a similar 2019 model with 61000 km sold for SAR 72000 in November 2023. Given the one-year difference and higher mileage, I adjusted the price downwards. Next, I looked at listed prices of similar 2018 models: SAR 49500 (115972 km), SAR 70000 (124000 km), SAR 65000 (124964 km), and SAR 67500 (80000 km). The average of these listed prices is around SAR 63000. Considering the car's average condition and the fact that listed prices are generally higher than selling prices, I adjusted the estimate slightly lower.
