To estimate the price of the 2023 BMW M850 Performance 4.4L I4 xDrive sedan with 10800 km mileage, I first looked at the new car prices for similar models. The 2025 BMW 8 Series Gran Coupe M850i xDrive starts at AED 760000. Given that the car in question is a 2023 model, I applied a 10% annual depreciation for one year, reducing the price by 10%, resulting in AED 684000. Next, I considered the listed price of a 2021 BMW M850 M Sport Individual XDrive with 78000 km, which is AED 299990. Given the significant difference in mileage and the fact that listed prices are generally higher than selling prices, I adjusted the price upwards for the lower mileage and newer model year. Combining these factors, I arrived at the final estimate.
