To estimate the price of the 2015 Ford Ranger I4 2.5L Double Cab Hi-Rider 4X4 M/T (Base+++), I first looked at the new car prices for different variants of the 2025 Ford Ranger. The closest variant in terms of engine size and configuration is the 2025 Ford Ranger 2.2L Double Cab (XLS) Hi-Rider (High) 4X4, which is priced at SAR 103385. Given that the car in question is a 2015 model, I applied a depreciation rate of 10% per year over 9 years. This results in a depreciation factor of approximately 0.387 (0.9^9). Applying this factor to the new car price of SAR 103385, the estimated price is SAR 40010. Additionally, considering the car's mileage of 99700 km and its average condition, I adjusted the price slightly downwards to account for wear and tear.
