To estimate the price of the 2014 Ford Expedition V8 5.4L XLT (Base) with 322000 km mileage and average condition, I considered several data points. First, I looked at the selling prices of similar cars. A 2013 model with 271000 km and average condition sold for 31000 SAR on 2024-01-02. Another 2014 model with 163000 km and average condition sold for 31000 SAR on 2024-04-04. A 2013 model with 281000 km and average condition sold for 30500 SAR on 2024-06-18. A 2013 model with 287000 km and average condition sold for 18000 SAR on 2024-08-03. A 2014 model with 149000 km and good condition sold for 45000 SAR on 2024-08-04. Considering the higher mileage and average condition of the target car, I adjusted the price downwards. I also noted the listed prices of similar cars, which ranged from 34000 to 40000 SAR but were not necessarily sold at those prices. Based on these data points, I estimated the market price.
