To estimate the price of the 2014 Infiniti QX80 V8 5.6L 7s Luxury with 143000 miles, I considered the following data points: 1) An offer accepted for a 2016 Infiniti QX80 5.6L V8 with 93280 miles at AED 90000 on 2023-11-05. Given the newer model year and lower mileage, this car would be valued higher than the 2014 model. 2) A listed price for a 2014 Infiniti QX80 5.6L V8 7s Luxury with 179500 miles at AED 50500. This car has higher mileage and is listed, not sold, so the actual selling price would likely be lower. 3) A listed price for a 2016 Infiniti QX80 5.6L V8 Limited with 137900 miles at AED 62000. This car is newer and has slightly lower mileage, but the Limited variant may command a higher price. Considering these factors, I adjusted for the older model year and higher mileage of the target car to arrive at the estimated price.
