To estimate the price of the 2018 Infiniti QX70 V6 3.7L Elite Sport, I first considered the selling prices of similar cars. The most relevant data points are the 2019 models with similar mileage and condition, which sold for AED 78000 and AED 67000. The 2017 model with good condition and similar variant sold for AED 79000. The 2018 model had an accepted offer of AED 90000, but this is higher than actual selling prices. The listed prices for 2018 models were AED 89500 and AED 83000, but these are typically higher than selling prices. Considering depreciation and the fact that the car is in good condition, I estimate the market price to be slightly lower than the 2019 models, around AED 75000.
