There is no data provided for selling prices, offers accepted, cars sold by dealers, or listed prices of similar cars. Therefore, I will use the new car price and apply depreciation logic. Assuming a new car price for a 2023 Hongqi H9 45TD I4 2.0L Turbocharged Flagship (Top) variant is AED 300,000, and considering a depreciation rate of 10% per year, the car would depreciate by 10% in one year. This results in a depreciation of AED 30,000. Therefore, the estimated price for the used car is AED 270,000.
