Given the lack of specific data points such as selling prices, offers accepted, or listed prices for similar cars, I will use the new car price and apply depreciation logic. Assuming a new GWM Wingle 5 Great Wall I4 2.2L Standard pick-up costs around 60,000 AED, and considering a depreciation rate of 10% per year, the car would depreciate approximately 30% over 3 years. This results in a depreciation of 18,000 AED, bringing the estimated value to 42,000 AED. However, considering the high mileage (161,700 km) and average condition, I will further reduce the price by 20%, resulting in an estimated value of 33,600 AED.
