To estimate the price of the 2019 BMW X1 sDrive 20i with 125439 km, I considered several data points. First, I looked at the selling prices of similar cars: a 2017 model with 131482 km sold for AED 54500, a 2019 model with 53000 km sold for AED 89000, and a 2018 model with 80000 km sold for AED 83000. The 2019 model is closest in year and condition but has significantly lower mileage, so I adjusted for higher mileage. I also considered an offer accepted for a 2019 model with 88600 km at AED 80000. For listed prices, a 2018 model with 125100 km was listed for AED 62500, and a 2019 model with 121000 km was listed for AED 95000 and AED 87700. Given the higher mileage of the target car, I adjusted the price downward from the higher end of the listed prices. Factoring in the condition and mileage, I estimated the market price accordingly.
