I started by examining the selling prices of similar cars. The most relevant data point is the 2022 Toyota Fortuner I4 2.7L GX2 4WD (Mid) with 97000 km sold for 103000 SAR on 2024-05-30. This car is the same variant as the target car but is a year older and has higher mileage. The 2022 Fortuner I4 2.7L GX2 2WD (Base) with 64500 km sold for 103000 SAR on 2024-04-16, indicating that the 4WD variant holds similar value despite higher mileage. The 2021 Fortuner I4 2.7L GX2 2WD (Base) with 177000 km sold for 77000 SAR on 2024-06-03, showing significant depreciation with high mileage. For listed prices, a 2023 Fortuner GX2 4WD (Mid) with 34000 km was listed for 115000 SAR, and another with 22500 km was listed for 117000 SAR, both delisted recently, suggesting a market price slightly lower than these listings. Considering the target car's lower mileage of 49983 km and being a 2023 model, I estimate its market price slightly above the 2022 model's selling price but below the recent listings.
