I started by examining the selling prices of similar cars. The most relevant data points are the 2020 Hyundai Sonata I4 2.5L Standard variants with selling prices of SAR 57000 (sold on 2024-01-01 and 2024-02-25) and a similar variant with a higher mileage sold for SAR 58500 on 2023-11-22. The car with the closest mileage to the target car (105000 km) sold for SAR 57000. The listed prices for similar cars range from SAR 55500 to SAR 70000, with the most relevant being SAR 58000 and SAR 62000 for cars with similar mileage. Considering the target car's mileage of 85164 km, which is lower than most sold cars, and its good condition, I estimate the market price to be slightly higher than the SAR 57000 selling price, but lower than the highest listed price.
