To estimate the price of the 2014 Nissan Xterra 4.0L V6 Titanium (Mid) with 215843 km mileage, I first considered the selling price of a similar car: a 2014 Nissan Xterra 4.0S V6 Titanium (Mid) with 98000 km sold for AED 37000 on 2023-08-29. Given the higher mileage of the target car, I adjusted the price downwards. Next, I looked at listed prices of similar cars: a 2014 Xterra 4.0L V6 Titanium (Mid) with the same mileage listed for AED 34000, and another with 198700 km listed for AED 32000. Considering these listings are higher than actual selling prices, I adjusted the estimate downwards. Finally, I factored in the condition of the car being average, which further reduces the price slightly.
