To estimate the price of the 2016 BMW X6 3.0L Twin Turbo I6 M Sport (Top) with 172000 km mileage and average condition, I considered several data points. First, the selling prices of similar cars: a 2016 BMW X6 X-Drive 50i with 205200 km sold for 73000 AED, a 2018 BMW X6 35i with 144067 km sold for 125000 AED, a 2015 BMW X6 50i with 158000 km sold for 84500 AED, another 2015 BMW X6 50i with 158000 km sold for 91300 AED, and a 2017 BMW X6 M-Kit 50i with 154700 km sold for 100000 AED. The closest match in terms of variant and condition is the 2018 BMW X6 35i, but it has a lower mileage and is a newer model. The accepted offer for a 2016 BMW X6 3.0L TC I6 with 161000 km was 84000 AED. Listed prices for similar cars were 88000 AED and 90000 AED. Considering the average condition and higher mileage of the target car, I adjusted the price downwards from the accepted offer and listed prices.
