To estimate the price of the 2024 BMW 840 V6 3.0L Twin Power Turbo Standard, I first considered the selling price of a similar 2022 BMW 840 I6 3.0L Twin Power Turbo (M Kit) with 93500 km mileage, which sold for SAR 210000 on 2024-05-02. Given the significant mileage difference, the 2024 model with only 1000 km should be valued higher. Next, I looked at the listed prices of similar cars. The closest match is a 2024 BMW 840 V6 3.0L Twin Power Turbo Standard with 1000 km listed for SAR 347000. Other listings include a 2023 BMW 840 Gran Coupe I6 3.0L Twin Power Turbo (M Sport) with 3800 km listed for SAR 380000, and a 2023 BMW 840 I6 3.0L Twin Power Turbo with 24000 km listed for SAR 350000. Considering these listings are generally higher than actual selling prices, I adjusted downwards. Finally, I noted the new car price for a different variant, the 2024 BMW 8 Series Coupe M850i xDrive, starting at SAR 599500, which is significantly higher due to being a different variant. Taking all these data points into account, I estimated the market price for the car.
