I started by examining the selling prices of similar cars. The 2019 Peugeot 3008 GT Line with similar specs and mileage sold for 72000 SAR recently, and the 2023 model sold for 107000 SAR. The 2021 model we are estimating is between these two in terms of age and mileage. The 2021 model listed for 93500 SAR with higher mileage (82000 km) than our target car (59000 km) provides a useful reference. Considering the depreciation and the average condition of the target car, I adjusted the price downward from the 2023 model's selling price and slightly above the 2019 model's selling price. The listed prices of 2023 models range from 97000 to 127000 SAR, but these are newer and have lower mileage, so they are not directly comparable. Based on these data points, I estimated the market price for the 2021 model.
