To estimate the price of the 2016 Nissan Sentra 1.6L S (Base) with 137100 km mileage, I considered the following data points: 1. A 2016 Nissan Sentra 1.6L I4 with 96200 km sold for 25500 AED on 2023-10-11. This car has a lower mileage and a slightly higher trim (SE), so it would be valued higher. 2. A 2016 Nissan Sentra 1.8L I4 with 147300 km sold for 19000 AED on 2023-12-18. This car has a higher engine capacity but similar mileage and condition. 3. Another 2016 Nissan Sentra 1.8L I4 with 106900 km sold for 26049 AED on 2023-12-23. This car has a higher engine capacity and lower mileage, so it would be valued higher. 4. A 2016 Nissan Sentra 1.8L I4 with 147300 km sold for 18000 AED on 2023-12-26. This car has a higher engine capacity but similar mileage and condition. 5. A 2016 Nissan Sentra 1.8L I4 with 174900 km sold for 16000 AED on 2024-02-09. This car has a higher engine capacity and higher mileage, so it would be valued lower. 6. Another 2016 Nissan Sentra 1.8L I4 with 174900 km sold for 15500 AED on 2024-02-10. This car has a higher engine capacity and higher mileage, so it would be valued lower. 7. Another 2016 Nissan Sentra 1.8L I4 with 174900 km sold for 13000 AED on 2024-02-26. This car has a higher engine capacity and higher mileage, so it would be valued lower. Considering the above data points, the 1.6L engine variant generally has a lower value compared to the 1.8L. Given the mileage and condition of the target car, I adjusted the price accordingly.
