To estimate the price of the 2017 Infiniti QX80 5.6L V8 4WD 8s Luxury with 99000 km mileage, I first considered the selling price of a similar car with almost identical mileage and condition, which sold for AED 110000 on 2024-01-10. This is the most reliable data point. Next, I looked at an offer accepted for a similar car with higher mileage (135700 km) at AED 110000 on 2023-10-03, which suggests that the price for a car with lower mileage should be higher. I also reviewed listed prices: a similar car with the same variant and mileage was listed for AED 140000, and another with slightly lower mileage (90600 km) was listed for AED 154000. These listed prices are generally higher than actual selling prices. Considering the selling price, accepted offer, and listed prices, I estimate the market price to be slightly higher than the selling price but lower than the listed prices.
