To estimate the price of the 2012 Dodge Durango Citadel V8 5.7L R/T (AWD) with 278000 km mileage in average condition, I considered several data points. The most relevant selling prices include a 2012 Dodge Durango V8 5.7L R/T (AWD) with 317029 km sold for 25000 SAR on 2023-10-05, and a 2012 Dodge Durango V8 5.7L R/T (AWD) with 148000 km sold for 34000 SAR on 2024-04-07. Given the higher mileage and average condition of the target car, I adjusted the price downward. Additionally, listed prices for similar cars range from 27000 SAR to 37500 SAR, but these are generally higher than actual selling prices. Considering the depreciation and the condition, I estimated the market price accordingly.
