To estimate the price of the 2018 BMW X6 M I6 3.0L Twin Power Turbo, I first considered the selling price of a similar 2019 BMW X6 M V8 4.4L Twin Power Turbo with 66000 km mileage, which sold for SAR 250000 in March 2024. Given that the car in question is a 2018 model with a smaller engine (I6 3.0L vs. V8 4.4L) and higher mileage (101000 km), I adjusted the price downwards. The listed prices of similar 2020 BMW X6 M 50i V8 4.4L Twin Power Turbo models range from SAR 236000 to SAR 317000, but these are for newer models with different engine specifications. Considering the depreciation and the differences in engine size and mileage, I estimated the market price accordingly.
