To estimate the price of the 2018 Nissan Sentra S I4 1.8L with 200500 km mileage, I first considered the selling prices of similar cars. The closest match is the 2019 Sentra 1.8L S (Base) with good condition and lower mileage (72500 km) sold for AED 36500 in January 2024. Another 2019 model with average condition and 81900 km sold for AED 33500 in September 2023. For older models, a 2016 Sentra 1.8L S (Base) with 174900 km sold for AED 13000 in February 2024. The 2018 Sentra with 165000 km had an accepted offer of AED 25000 in December 2023, and another with 158700 km had an accepted offer of AED 28000 in July 2024. Considering the higher mileage of the target car, I adjusted the price downwards from these offers. The listed prices for similar 2018 models were AED 30000 and AED 34500, but these are typically higher than actual selling prices. Given the car's age, mileage, and condition, I estimate the market price to be slightly lower than the accepted offers, reflecting the higher mileage and depreciation.
