I started by looking at the selling prices of similar cars. The closest match is the 2015 Nissan Altima 2.5L I4 SV with 182000 km sold for 19500 AED on 2024-04-30. This car is very similar in terms of variant and condition. Other selling prices for the SL variant, which is higher than SV, were 31500 AED and 22500 AED, but these are not as relevant due to the different trim level. The accepted offers for SL and SE variants ranged from 19500 AED to 29000 AED, but again, these are not as relevant due to different trims. Considering the most relevant data point of 19500 AED for a similar SV variant and adjusting slightly for the higher mileage of the car in question, I arrived at my estimate.
