To estimate the price of the 2017 Toyota Fortuner I4 2.7L GX2 2WD (Base) with 188597 km mileage and average condition, I considered the following data points: 1) A 2017 model with 241000 km in average condition sold for 64000 SAR on 2024-02-27. 2) A 2016 model with 224500 km in average condition sold for 62000 SAR on 2024-03-31. 3) A 2015 model with 201000 km in average condition sold for 60500 SAR on 2024-07-25. 4) A 2015 model with 176000 km in average condition sold for 52500 SAR on 2024-05-11. 5) A 2016 model with 222000 km in average condition sold for 65500 SAR on 2023-12-31. Considering the mileage and condition of the target car, I estimated its price to be slightly higher than the 2015 models but lower than the 2016 and 2017 models with higher mileage.
