The car to be estimated is a 2016 Nissan X-Trail I4 2.5L S 2WD (7-Seater) (Base+) with 193,000 km mileage in good condition. The most relevant data point is a similar car with the same variant and higher mileage (233,000 km) sold for 34,500 SAR in May 2024. Another similar car with lower mileage (126,000 km) sold for 48,000 SAR in March 2024. Considering the target car's mileage and condition, its value should be between these two prices. The car with 233,000 km was listed for 34,500 SAR, which matches its selling price, indicating a consistent market value. Given the target car's good condition and lower mileage than the 233,000 km car, a reasonable estimate is slightly higher than 34,500 SAR but lower than 48,000 SAR.
