I started by looking at the selling price of a similar 2016 Mercedes GLC250 with the same variant and condition, which sold for SAR 50,000 on 2024-09-04. This car had a higher mileage of 213,000 km compared to the target car's 186,779 km. The lower mileage of the target car suggests it could be valued slightly higher. I also considered a listed price of SAR 52,000 for a similar car with the same variant and mileage, which was delisted on 2024-09-05, indicating it might not have sold at that price. Given the selling price and the listed price, I estimated the market value of the target car to be slightly above SAR 50,000 but below SAR 52,000, considering its lower mileage and similar condition.
