To estimate the price of the 2019 BMW 520 I4 2.0L Twin Power Turbo Standard with 84400 km mileage, I first looked at the selling price of a similar 2018 model with 126000 km mileage, which sold for SAR 72000 in May 2024. Given the 2019 model has lower mileage and is a year newer, it should be valued higher. Next, I reviewed 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 110000 km listed for SAR 113500. These listed prices are generally higher than actual selling prices. Considering the condition and mileage of the target car, I adjusted the price downwards from the listed prices but higher than the 2018 sold price. Factoring in depreciation and market trends, I arrived at a reasonable estimate.
