The car to be estimated is a 2020 BMW X7 xDrive M50i V8 4.4L TwinTurbo with 152100 km mileage. The closest match in the listings is a 2019 BMW X7 Mkit Xdrive 50i V8 4.4L Twin Turbo with 118000 km listed for AED 206000, delisted recently. Considering the higher mileage of the target car, a depreciation adjustment is necessary. Other 2019 X7 50i variants with lower mileage (around 99000 km) are listed between AED 225000 and AED 238000. Given the target car's higher mileage and average condition, a further reduction is warranted. The 2020 X7 40i with 60500 km is listed at AED 290000, but it's a different variant and has much lower mileage. Factoring in the target car's higher mileage and average condition, the estimated market price is adjusted downward from the closest comparable listings.
