The closest match is a 2019 Hyundai Tucson I4 1.6L Smart (Base) with 147000 km sold for 62500 SAR on 2024-07-28. Considering the lower mileage of the target car, it should be valued higher. A 2019 Tucson I4 2.0L Smart (Base) with 116000 km sold for 65000 SAR on 2024-04-26, indicating a higher price for lower mileage.
