To estimate the price of the 2021 Nissan Sunny 1.5L SV S (Base), I first considered the accepted offer for a similar 2021 Nissan Sunny 1.6L S (Base) at AED 32000. This provides a baseline for the lower end of the market. Next, I reviewed the listed prices for the 1.5L SV variant, which ranged from AED 37990 to AED 44990. These listings are likely higher than actual selling prices, so I adjusted downwards. The car in question has average condition and mileage similar to the listed cars, suggesting a price slightly below the average of the listings. Considering the accepted offer and the listed prices, I estimated the market price to be slightly below the average of the listings, around AED 37000.
