To estimate the price of the 2015 Nissan Sentra SV 1.8L I4, I first considered the offers accepted by sellers for similar cars. A 2014 Sentra with higher mileage (125900 miles) had an accepted offer of AED 16000, while a 2016 Sentra with much higher mileage (161000 miles) had an accepted offer of AED 18500. A 2017 Sentra with lower mileage (38700 miles) had an accepted offer of AED 22500. The 2015 model year falls between the 2014 and 2016 models, and its mileage is lower than the 2016 model but higher than the 2017 model. Considering these factors, the estimated price should be slightly higher than the 2014 model's accepted offer but lower than the 2016 model's accepted offer. I also looked at listed prices for reference: a 2017 Sentra with similar specs and lower mileage was listed for AED 24000, but this is likely higher than the actual selling price. Based on these data points, I estimate the market price for the 2015 Sentra to be around AED 17000.
