The closest match is the 2020 Hyundai Sonata I4 2.4L Standard with 127900 km sold for 57000 SAR on 2024-01-01. Considering the lower mileage of the target car, it should be valued higher.

Considering the selling prices and the listed prices, I estimate the market price of the target car to be slightly lower than the highest listed price due to negotiation and market conditions.
