To estimate the price of the 2017 Infiniti QX70 V6 3.7L Elite Sport 3.7L (Top) with 73000 km mileage, I first considered the selling prices of similar cars. A 2017 model with 61000 km in good condition sold for 79000 AED in June 2023, and another with 121800 km in average condition sold for 68000 AED in July 2023. Given the target car's mileage and condition, its value should be closer to the 79000 AED sale. I also noted a 2019 model with 80000 km sold for 78000 AED in May 2024, indicating a slight depreciation trend. The listed prices for similar cars range from 68000 to 89500 AED, but these are typically higher than actual selling prices. Considering these factors, the estimated market price is slightly below the 79000 AED sale due to the higher mileage and time elapsed since that sale.
