Given the lack of specific data points such as selling prices, offers accepted, and listed prices, I will use the new car price and apply depreciation logic. Assuming a new 2023 Mercedes C43 AMG I4 2.0L Standard sedan has a price of 300,000 AED, and considering a depreciation rate of 10% per year, the car would depreciate by 30,000 AED in the first year. Since the car is in average condition and has 9800 miles, I will consider an additional depreciation of 5%, which is 15,000 AED. Therefore, the estimated price is calculated as 300,000 AED - 30,000 AED - 15,000 AED.
