To estimate the price of the 2015 Ford Flex V6 3.5L SEL LTH (Mid+), I considered the selling prices of similar cars. The closest match is a 2015 Ford Flex V6 3.5L with 277000 km mileage, sold for 31300 SAR on 2023-10-11. Another 2015 model with 218000 km sold for 25000 SAR on 2024-05-31. Given the target car's mileage of 238000 km and its higher trim (SEL LTH), it should be valued slightly higher than the 25000 SAR car but lower than the 31300 SAR car. The listed price of a similar car is 38000 SAR, but this is likely inflated. Considering these factors, I estimate the market price to be between 28000 and 30000 SAR.
