To estimate the price of the 2015 Toyota Fortuner I4 2.7L GX2 2WD (Base) with 251000 km mileage, I considered the following data points: 1. A similar 2015 model with 201000 km sold for 60500 SAR on 2024-07-25. 2. A 2015 model with 176000 km sold for 52500 SAR on 2024-05-11. 3. A 2014 model with 248000 km sold for 50000 SAR on 2024-02-26. 4. A 2013 model with 314000 km sold for 41000 SAR on 2024-08-22. 5. A 2014 model with 154000 km sold for 47500 SAR on 2024-06-01. 6. Listed prices for similar 2015 models range from 48000 to 60500 SAR. Considering the higher mileage of the target car (251000 km) and its average condition, I adjusted the price downwards from the higher end of the selling prices and listed prices, while also factoring in the depreciation over time.
