To estimate the price of the 2023 BMW X6 M 50i V8 4.4L Standard, I first considered the listed prices of similar cars. The closest match is a 2023 BMW X6 M 50i V8 4.4L with 37000 km listed for SAR 420,000 and another with 38000 km listed for SAR 380,000. These cars have higher mileage than the target car, which has 17500 km. The lower mileage of the target car suggests a higher value. The 2025 new model starts at SAR 685,000. Assuming a 15% annual depreciation, the 2023 model would depreciate approximately 30% from the new price, suggesting a value around SAR 479,500. Considering the listed prices and the lower mileage, I estimate the market price to be slightly higher than the listed prices but lower than the depreciated new price estimate.
