I started by examining the selling prices of similar cars. The most relevant data point is the 2015 BMW 730 3.0TC I6 with average condition and 103350 km mileage, sold for AED 52000 on 2024-05-25. Another 2015 BMW 730 Li 3.0L I6 with good condition and 185000 km mileage sold for AED 53000 on 2023-07-31. Considering the target car's higher mileage of 177000 km and average condition, its value should be slightly lower than these. The 2013 BMW 730 3.0L I6 with average condition and 55500 km mileage sold for AED 38000, but it's older, so less relevant. The listed prices show a range from AED 41000 to AED 54000, with the most comparable being AED 41000 for a car with 167900 km mileage. Given these data points, I estimate the market price to be slightly below the lower end of the selling prices due to the higher mileage and average condition.
