To estimate the price of the 2020 Nissan X-Trail I4 2.5L S 4WD (Base+), I considered the following data points: 1) A 2020 Nissan X-Trail 2.5L I4 S 2WD (Base) with 76500 km sold for AED 62099 on 2024-05-05. 2) A 2020 Nissan X-Trail SL 2.5L I4 (Top) with 90000 km sold for AED 74500 on 2024-07-18. 3) An offer of AED 67000 was accepted for a 2020 Nissan X-Trail S 2WD (Base) with 87100 km on 2023-09-25. 4) An offer of AED 70000 was accepted for a 2020 Nissan X-Trail SV (Mid) with 92000 km on 2023-10-17. 5) An offer of AED 67500 was accepted for a 2020 Nissan X-Trail SV (Mid) with 93000 km on 2024-01-22. 6) An offer of AED 59000 was accepted for a 2020 Nissan X-Trail S 2WD (Base) with 76500 km on 2024-05-14. 7) An offer of AED 76000 was accepted for a 2020 Nissan X-Trail SL (Top) with 90000 km on 2024-07-16. Considering the car's higher mileage (102360 km) and its 4WD feature, I adjusted the price slightly higher than the 2WD variants but lower than the top trims.
