The closest match is the 2013 Ford Expedition V8 5.4L EL XLT 4WD (Mid+) with 322000 km sold for 27000 SAR in November 2023. Given that the target car has a similar mileage but is in average condition and a slightly lower trim, its value should be slightly lower. Another relevant data point is the 2013 Ford Expedition V8 5.4L XLT (Base) with 271000 km sold for 31000 SAR in January 2024, but this car had a lower mileage and was in average condition. The 2013 Ford Expedition V8 5.4L XLT (Base) with 273000 km sold for 35500 SAR in September 2023, but it was in good condition. The most recent sale is the 2013 Ford Expedition V8 5.4L XLT (Base) with 281000 km sold for 30500 SAR in June 2024, also in average condition. Considering the target car's higher mileage and average condition, its value should be lower than these. The listed prices for similar cars range from 30000 to 42500 SAR, but these are generally higher than actual selling prices. Therefore, I estimate the market price to be slightly lower than the lowest selling price of similar cars in average condition.
