To estimate the price of the 2014 Ford Expedition V8 5.4L EL XLT (Base+) with 206500 km mileage, I focused on similar cars with the same variant and condition. The most relevant data point is a 2013 Ford Expedition EL XLT (Base+) with 196000 km sold for 39000 SAR on 2023-11-18. Another 2012 model with the same variant and mileage of 206500 km sold for 28500 SAR on 2023-11-03. A 2013 model with 154800 km sold for 36000 SAR on 2023-10-18. Considering the target car's mileage and condition, I adjusted the price slightly higher than the 2012 model but lower than the 2013 model with less mileage. The listed price of a similar 2014 model with 224000 km was 43000 SAR, but this is typically higher than actual selling prices. Therefore, I estimated the market price by averaging these relevant data points and considering depreciation and mileage differences.
