I started by looking at the selling prices of similar used cars. The closest match is the 2020 BMW X5 M-Kit 40i X-Drive 3.0L Twin Power Turbo I6 with a selling price of 220000 AED, sold on 2023-05-06. This car has a higher mileage (99500 km) and is in good condition. Another relevant data point is the 2018 BMW X5 3.0L I6 TC with a selling price of 155000 AED, sold on 2023-07-06, which has a lower mileage (76000 km) and is in good condition. The 2019 BMW X5 XDrive 50i 4.4L V8 sold for 210000 AED on 2024-07-09, but it has a different engine variant. Considering the target car's average condition and mileage (84076 km), I adjusted the price downwards from the 220000 AED benchmark. The 2018 BMW X5 35i 3.0L I6 Twin Turbo M kit with average condition and higher mileage (149000 km) sold for 87000 AED, which also influenced the downward adjustment.
