To estimate the price of the 2019 Nissan Sunny I4 1.5L S (Base) with 120,000 km mileage, I focused on the selling prices of similar cars. The most relevant data point is the 2019 Nissan Sunny 1.5L I4 S (Base) with 140,500 km sold for 25,500 AED on 2024-04-22. Another similar car, a 2019 Nissan Sunny 1.5L I4 S (Base) with 116,736 km, sold for 20,000 AED on 2024-08-07. Considering the target car's mileage of 120,000 km, which is between these two, and the fact that the most recent sale of a similar car was for 20,000 AED, I estimate the price to be slightly above 20,000 AED but below 25,500 AED. Given the average condition and mileage, I estimate the market price to be 22,000 AED.
