I started by looking at the selling prices of similar cars. The most relevant data point is the 2023 Haval Dargo I4 2.0L Adventure (Top) with 26000 km sold for 71500 SAR on 2024-08-17. This car is very similar to the target car in terms of model year, variant, and condition, but has slightly higher mileage. Another relevant data point is the 2022 Haval Dargo I4 2.0L Adventure (Top) with 20000 km sold for 71000 SAR on 2024-03-20. This car is a year older but has similar mileage and condition. The listed prices show a 2023 model with 31000 km listed for 82500 SAR, which is higher than the selling prices, indicating that listed prices are generally higher than actual selling prices. Considering the target car's lower mileage of 21000 km and good condition, I estimate its market price slightly higher than the 71500 SAR selling price but lower than the 82500 SAR listed price.
