To estimate the price of the 2019 BMW 520 I4 2.0L Twin Power Turbo Standard with 85000 km mileage, I first considered the selling price of a similar 2018 model with 126000 km sold for SAR 72000 in May 2024. Given the 2019 model has lower mileage, it should be valued higher. Next, I looked at listed prices of similar 2019 models: one with 85000 km listed for SAR 110500, another with 73050 km listed for SAR 118000, and another with 58500 km listed for SAR 122000. These listed prices are generally higher than actual selling prices. Considering the depreciation and the average condition of the car, I adjusted the price downwards from the listed prices but higher than the 2018 sold price. Factoring in the market trends and the condition, I arrived at a reasonable estimate.
