I started by examining the selling prices of similar cars. A 2020 BMW X2 sDrive 20i with 47000 km and average condition sold for AED 101600 on 2023-12-27. Another 2021 model with 28000 km and good condition sold for AED 106000 on 2023-11-04. A 2021 model with 25000 km and average condition sold for AED 99000 on 2024-03-04. The 2020 model with similar mileage and condition to the target car sold for AED 101600, which is a relevant data point. Next, I looked at offers accepted by sellers. A 2020 model with 47000 km had an offer accepted for AED 104000 on 2023-12-23, and another with 47500 km had an offer accepted for AED 86500 on 2024-03-25. The accepted offer of AED 86500 is lower, possibly due to market conditions or negotiation. Dealer sales show a 2020 model with 20038 km sold for AED 99441.5 on 2023-12-11, and another with 64546 km sold for AED 93491.5 on 2024-05-23. The dealer sale with 54718 km sold for AED 90941.5 on 2024-05-04. Considering the target car's good condition and 42000 km mileage, I estimate its market price to be slightly above the lower end of the accepted offers and dealer sales, but below the higher selling prices, around AED 95000.
