To estimate the price of the 2018 Nissan X-Trail I4 2.5L S AWD (5-Seater) (Mid) with 97000 km mileage, I considered the following data points: 1) A similar car with the same variant and good condition but higher mileage (125000 km) sold for 56000 SAR on 2023-10-15. 2) Another similar car with the same variant and good condition but higher mileage (114000 km) sold for 60000 SAR on 2024-03-26. 3) A similar car with the same variant and good condition but higher mileage (110276 km) sold for 45000 SAR on 2024-08-26. 4) A similar car with a different variant (S 2WD) and good condition but lower mileage (91000 km) sold for 59000 SAR on 2024-09-03. Considering the lower mileage of the target car and its good condition, I estimated the price to be slightly higher than the average of these data points.
