The car to be estimated is a 2023 Hongqi H9 50TD V6 3.0L Turbocharged Deluxe (Mid) with 19000 km mileage. The only data point available is a listed price for a 2023 Hongqi H9 45TD I4 2.0L Turbocharged Flagship (Top) variant with 15500 km mileage, listed at AED 154500. The 50TD V6 3.0L is a higher engine variant than the 45TD I4 2.0L, which typically means a higher price. However, the listed car is a Flagship (Top) variant, which might have more features than the Deluxe (Mid) variant. Considering the engine size difference and the fact that listed prices are often higher than actual selling prices, I estimate the market price for the 50TD V6 3.0L Deluxe (Mid) to be slightly lower than the listed price of the 45TD I4 2.0L Flagship (Top).
