I analyzed the selling prices of similar cars first. The most relevant data points are the four cars sold in late 2023 and early 2024, all of which are 2015 Ford Ecosport I4 1.5L Ambiente (Base) with similar mileage and condition. These cars sold for SAR 25000 (three instances) and SAR 21000. Given the consistency of the SAR 25000 selling price, it is a strong indicator of the market value. The car with lower mileage (147000 km) sold for SAR 21000, suggesting a slight depreciation for higher mileage. The listed prices of similar cars range from SAR 21000 to SAR 30000, but these are generally higher than actual selling prices. Considering the car in question has 184695 km, which is slightly lower than the average mileage of the sold cars, I estimate the price to be slightly below SAR 25000 but above SAR 21000.
