First, I considered the selling price of a similar 2022 BMW X5 3.0L TC I6 with 6100 km mileage, sold for AED 316,000 on 2023-06-26. This car is very similar in variant and condition. Another 2020 BMW X5 M-Kit 40i with higher mileage (99,500 km) sold for AED 220,000 on 2023-05-06. The 2022 model with lower mileage is more relevant. An offer was accepted for a 2022 BMW X5 3.0 Turbo I6 Black Edition with 20,600 km for AED 315,500 on 2023-09-16, indicating a similar market value. Listed prices for similar cars were AED 255,000 and AED 260,000, but these are typically higher than actual selling prices. Considering depreciation and the mileage of the car to be estimated (50,000 km), I adjusted the value slightly lower than the recent selling price of AED 316,000, accounting for higher mileage and market trends.
