To estimate the price of the 2020 Toyota Fortuner V6 4.0L VX1 (4X4) with 81000 km mileage, I primarily considered the actual selling prices of similar cars. The most relevant data point is a car of the same model, variant, and mileage sold for SAR 111000 on 2024-06-19. Other selling prices of lower variants (I4 2.7L GX2) ranged from SAR 88500 to SAR 97500, but these are less relevant due to different engine sizes and trims. The listed prices for similar cars were SAR 111000 and SAR 107000, which align closely with the actual selling price. Given the consistency of these prices and the recent sale date, I estimate the market price accordingly.
