I started by looking at the selling prices of similar cars. The first car, with 15000 km mileage and average condition, sold for 140000 SAR on 2024-01-08. The second car, with 33000 km mileage and good condition, sold for 138000 SAR on 2023-07-28. The third car, with 52000 km mileage and average condition, sold for 103000 SAR on 2024-05-27. Given that the car in question has a lower mileage of 17000 km and is in good condition, it should be valued higher than the third car but comparable to the first two. Next, I looked at the listed prices. The closest match is a car with 17000 km listed for 140500 SAR. Other listings range from 100000 SAR to 145000 SAR, but these have higher mileages. Considering the selling prices and the listed prices, I estimated the market price for the car in question.
