Given the lack of specific data points such as selling prices, offers accepted, or listed prices for similar cars, I will use the depreciation logic based on the new car price. Assuming a new JAC M4 Standard coupe costs around 60,000 AED in 2016, and applying a 10% depreciation per year over 8 years (2016 to 2024), the calculation would be as follows: 60,000 AED * (0.9^8) = 25,971 AED. Considering the high mileage of 135,000 miles, which is significantly above average, I will further reduce the estimated price by 20% to account for the wear and tear. Therefore, the final estimated price is approximately 20,777 AED.
