To estimate the price of the 2023 BMW 840 I6 3.0L Twin Power Turbo Standard sedan with 25000 km mileage, I first looked at the selling price of a similar 2022 model with higher mileage (93500 km) and in good condition, which sold for SAR 210000 in May 2024. Given the lower mileage and newer model year of the target car, its value should be higher. Next, I considered the listed prices of similar 2023 models with similar mileage, which ranged from SAR 293500 to SAR 350000. These listed prices are generally higher than actual selling prices. The new car price for a different variant (M850i xDrive) is SAR 599500, but this is not directly comparable due to the different variant. Considering the depreciation and the condition of the car, I adjusted the price accordingly.
