To estimate the price of the 2020 Infiniti QX80 V8 5.6L ProACTIVE (Top) with 70300 km mileage, I analyzed the listed prices of similar cars. The closest matches are the 2019 and 2021 Infiniti QX80 5.6L V8 variants with similar mileage and specs. The listed prices for 2019 models range from AED 90000 to AED 126500, with most prices clustering around AED 105000 to AED 115000. The 2021 models are listed between AED 100000 and AED 135000. Given that the target car is a 2020 model, its price should logically fall between the 2019 and 2021 models. Considering the car's good condition and Canadian specs, I estimate the market price to be slightly higher than the average 2019 model but lower than the 2021 models.
