A 2019 X-Trail S 2WD (Base) with average condition and 69300 km mileage sold for AED 65000 on 2024-04-07. This is a close match in terms of variant and condition. Another 2020 X-Trail S 2WD (Base) with average condition and 76500 km sold for AED 62099 on 2024-05-05. These prices suggest a range of AED 62000 to AED 65000 for similar cars. The listed prices for 2019 X-Trail S 2WD (Base) range from AED 69990 to AED 79990, but these are typically higher than actual selling prices.
