There is no data provided for selling prices, offers accepted, cars sold by dealers, or listed prices of similar cars. Additionally, there is no information on the price of new GCC-spec cars. Given the lack of specific data, I will use a general depreciation logic. Assuming a new BMW X3 M 3.0L I6 Standard in 2013 was approximately 250,000 AED, and applying a 10% depreciation per year over 11 years, the estimated value would be calculated as follows: 250,000 AED * (0.9^11) = 87,500 AED. Considering the car's average condition and mileage, I will adjust the price slightly lower to account for these factors.
