To estimate the price of the 2015 Nissan Sentra 1.8L S (Base) with 285,000 km mileage, I first considered the selling prices of similar cars. A 2016 Sentra 1.8L S with 174,900 km sold for AED 13,000 in February 2024. Given the higher mileage of the target car, its value would be lower. A 2015 Sentra 1.6L S with 240,584 km sold for AED 14,000 in September 2024, and a 2015 Sentra SV with 149,023 km sold for AED 15,500 in November 2024. These prices suggest a range for similar models. The listed prices for 2015 Sentra 1.8L S models were around AED 18,500, but these are typically higher than selling prices. Considering the higher mileage and the depreciation since the last sale, I estimate the market price to be slightly lower than the lowest selling price of similar models.
