I started by examining the selling prices of similar cars. The most relevant data points are: a 2015 BMW 520 2.0L I4 with 168500 km sold for AED 35000 on 2023-09-11, a 2015 BMW 520 2.0L V4 with 175000 km sold for AED 37500 on 2024-03-18, and a 2015 BMW 520 with 189000 km sold for AED 38000 on 2023-07-30. These prices suggest a range between AED 35000 and AED 38000. Next, I considered offers accepted by sellers: AED 51000 for a car with 130000 km, AED 36000 for a car with 175000 km, and AED 35000 for a car with 210300 km. The accepted offer of AED 36000 for a car with similar mileage is particularly relevant. Finally, I looked at listed prices, which are generally higher than selling prices. The most relevant listings are AED 39000 and AED 38000 for cars with similar mileage. Considering all this data, the estimated market price for the car is likely around AED 36000, aligning with the accepted offer and the lower end of the selling price range.
