I started by examining the selling prices of similar cars. The most relevant data point is a 2021 Chevrolet Captiva LT FWD (Base) with 68000 km sold for 38000 SAR on 15 Nov 2024. Another similar car with 82000 km sold for 40000 SAR on 5 Nov 2024. These cars have similar mileage and condition to the target car. The third car, an LT AWD (Mid) variant with 42000 km, sold for 43500 SAR on 15 Oct 2024, but it has a different drivetrain and trim, so it's less relevant. Next, I looked at the listed prices. The most relevant is a car with 68000 km listed for 39000 SAR, which is not delisted, indicating it might not have sold at that price. Other listings range from 37500 SAR to 57000 SAR, but many are delisted, suggesting they were priced too high. Considering the selling prices and the current listing, I estimate the market price for the target car, which is in good condition and has 66000 km, to be slightly higher than the 38000 SAR sold price but lower than the 39000 SAR listing, as it is in better condition than the average condition cars sold.
