To estimate the price of the 2015 Toyota Fortuner I4 2.7L GX2 4WD (Mid) with 216000 km mileage, I considered several data points. First, I looked at the selling prices of similar cars. A 2015 Fortuner GX2 2WD (Base) with 176000 km sold for 52500 SAR in May 2024. A 2014 Fortuner GX2 4WD (Mid) with 248000 km sold for 50000 SAR in February 2024. A 2017 Fortuner GX2 2WD (Base) with 241000 km sold for 64000 SAR in February 2024. A 2016 Fortuner GX2 2WD (Base) with 224500 km sold for 62000 SAR in March 2024. The closest match in terms of variant and mileage is the 2014 Fortuner GX2 4WD (Mid) which sold for 50000 SAR. Considering the year difference and the slightly lower mileage of the target car, I adjusted the price upwards slightly. Additionally, the listed prices for similar cars range from 56000 to 62500 SAR, but these are generally higher than actual selling prices. Therefore, I estimated the market price to be slightly lower than the average of these listings.
