To estimate the price of the 2019 BMW X2 sDrive 20i with 102000 km mileage, I first looked at the selling prices of similar cars. The 2021 BMW X2 sDrive 20i with 28000 km sold for AED 106000, the 2020 model with 47000 km sold for AED 101600, and another 2021 model with 25000 km sold for AED 99000. These prices suggest a depreciation trend. Next, I considered the listed prices of similar cars. A 2019 BMW X2 with the same mileage is listed for AED 99750, while a 2020 model with 103000 km was listed for AED 72500. Given the higher mileage and average condition of the target car, I adjusted the price downward from the listed prices. The average of the selling prices is around AED 102200, but considering the higher mileage and average condition, I estimated a lower value.
