I started by examining the selling prices of similar cars. The most relevant data points are the 2016 BMW X5 3.0L I6 TC with 105,000 km sold for 89,500 AED on 2024-07-26, and the 2016 BMW X5 X Drive 35i 3.0L V6 with 165,300 km sold for 68,500 AED on 2024-09-10. The 2018 BMW X5 3.0L I6 TC with 76,000 km sold for 155,000 AED on 2023-07-06 is also relevant but has a higher price due to being a newer model. The 2017 model in question has a mileage of 98,873 km, which is closer to the 2016 models. Considering the depreciation and the fact that the 2017 model is newer than the 2016 models, I estimate the price to be slightly higher than the 2016 models but lower than the 2018 model. The listed prices for 2017 models range from 108,000 AED to 139,750 AED, but these are typically higher than actual selling prices. Taking all this into account, I estimate the market price to be around 105,000 AED.
