To estimate the price of the 2018 Dodge Durango V6 3.6L GT (RWD) (Mid) with 129,000 km mileage and average condition, I first considered the selling price of a similar 2018 model with 117,071 km and good condition, which sold for 75,000 SAR in July 2023. Given the higher mileage and average condition of the target car, its value would be lower. A 2017 model with average condition and higher mileage (213,000 km) sold for 53,000 SAR in March 2024, providing a lower bound. A 2020 model with average condition and similar mileage (106,000 km) sold for 92,874 SAR in July 2024, but being a newer model, it would be priced higher than the 2018 model. The listed price of a similar 2018 model with lower mileage (104,000 km) was 73,000 SAR in January 2024, suggesting a market expectation. Considering these data points, the estimated price for the target car is adjusted to reflect its higher mileage and average condition, leading to a final estimate slightly below the 73,000 SAR listing.
