Given the lack of specific data points such as selling prices, offers accepted, and listed prices, I will use the depreciation logic based on the new car price. Assuming a new 2015 Mercedes GLA45 AMG had an approximate price of 250,000 AED, and considering a depreciation rate of 10% per year, the car would depreciate as follows: 2016: 225,000 AED, 2017: 202,500 AED, 2018: 182,250 AED, 2019: 164,025 AED, 2020: 147,622 AED, 2021: 132,860 AED, 2022: 119,574 AED, 2023: 107,616 AED, 2024: 96,854 AED. Given the car's average condition and high mileage, I would further reduce the price by approximately 15%, resulting in an estimated market price.
