To estimate the price of the 2015 Toyota Fortuner I4 2.7L GX2 2WD with 351,000 km mileage, I first considered the selling prices of similar cars. A 2015 model with 251,000 km sold for 49,500 SAR on 2024-09-18, and another with 201,000 km sold for 60,500 SAR on 2024-07-25. A 2015 model with 176,000 km sold for 52,500 SAR on 2024-05-11. The 2013 model with 314,000 km sold for 41,000 SAR on 2024-08-22. The car in question has higher mileage than these examples, suggesting a lower price. The listed prices for similar cars with high mileage were 49,000 SAR and 32,000 SAR, with the latter delisted, indicating it might have been too low. Considering these data points, the high mileage and average condition of the car, I estimate the market price to be slightly lower than the lowest selling price of a 2015 model with lower mileage.
