To estimate the price of the 2023 BMW X7 I6 3.0L Twin Power Turbo xDrive 50i (Top) with 23000 km mileage, I first looked at the selling price of a similar 2022 model with 6000 km mileage, which sold for SAR 232700 on 2024-01-30. Given the lower mileage and slightly older model, this provides a baseline. Next, I considered the new car price for the 2024 BMW X7 xDrive50i, which starts at SAR 525000. Applying a 10% annual depreciation, the 2023 model would be approximately SAR 472500. I also reviewed listed prices of similar cars: a 2023 model with the same variant and mileage listed for SAR 399000, and another 2023 model with 8200 km listed for SAR 380000. Considering these data points, the selling price of SAR 232700 for the 2022 model, and the depreciation from the new car price, I estimated the market price for the 2023 model.
