To estimate the price of the 2020 Nissan X-Trail I4 2.5L S 2WD (5-Seater) (Base) in good condition, I first considered the selling prices of similar 2018 models. The 2018 X-Trail S AWD (5-Seater) (Mid) with average condition sold for SAR 40,000 and SAR 45,000, while the S 2WD (7-Seater) (Base+) sold for SAR 39,000. The 2018 S AWD (7-Seater) (Mid+) in good condition sold for SAR 56,000. These prices suggest a range for older models. Next, I looked at the listed prices for the same 2020 model with lower mileage, which were SAR 69,500 and SAR 65,000. Considering the higher mileage of the car in question and its good condition, I adjusted the price slightly lower than the listed prices but higher than the older models' selling prices, reflecting its newer model year and condition.
