To estimate the price of the 2022 BMW 520 I4 2.0L Twin Power Turbo with 86000 km mileage in average condition, I first looked at the selling prices of similar cars. A 2022 model with 20000 km sold for 190000 SAR in February 2024, and another with 30000 km sold for 173500 SAR in May 2024. Given the higher mileage and average condition of the target car, its value would be lower. Next, I reviewed listed prices: a similar car with 86000 km is listed for 145000 SAR, and another with 60000 km was listed for 153000 SAR. Considering the higher mileage and average condition, the target car's value would be closer to the lower end of these listings. Factoring in the depreciation and market trends, I arrived at the final estimate.
