To estimate the price of the 2013 Ford Expedition V8 5.4L EL XLT (Base+) with 288897 km mileage, I first considered the selling prices of similar cars. A similar variant, EL XLT (Base+), with 280000 km sold for 40000 SAR in June 2023. Another similar car with 287000 km sold for 18000 SAR in August 2024, but this was an outlier. The average condition XLT (Base) variant with 271000 km sold for 31000 SAR in January 2024. The listed prices for EL XLT (Base+) variants ranged from 30000 to 42500 SAR, but these are typically higher than actual selling prices. Considering the car's average condition and mileage, I estimate the market price to be slightly lower than the 40000 SAR sale due to depreciation and condition, but higher than the 18000 SAR outlier, aligning closer to the 31000 SAR sale of a similar variant.
