I started by examining the selling prices of similar cars. A 2015 BMW 520 2.0L I4 with 168500 km sold for AED 35000 in September 2023, and another with 175000 km sold for AED 37500 in March 2024. These cars are similar in age and engine type but have higher mileage than the target car. Next, I looked at offers accepted by sellers. A 2015 BMW 520 2.0L I4 with 130000 km had an offer accepted at AED 51000 in October 2023, which is closer in mileage to the target car. For listed prices, a 2015 BMW 520 2.0 I4 with 154000 km was listed for AED 41500, and another with 171000 km was listed for AED 44000. Considering the target car's mileage of 130300 km and its M Sport variant, which typically commands a premium, I estimated the market price by weighing these data points, giving more weight to the accepted offer of AED 51000 and adjusting slightly downwards for market conditions and the car's average condition.
