To estimate the price of the 2012 Ford Flex V6 3.5L SEL (Mid) with 290000 km mileage, I first looked at the selling prices of similar cars. The 2013 Ford Flex V6 3.5L with similar mileage and condition sold for SAR 16500 on 2023-10-25. Another 2013 model with lower mileage (203400 km) sold for SAR 24000 on 2023-11-28, SAR 21500 on 2023-12-07, and SAR 21000 on 2024-03-17. Given the 2012 model is a year older, I adjusted the price downwards. The listed prices for similar cars ranged from SAR 16500 to SAR 33000, but the most relevant listing for a 2012 model with similar mileage was SAR 21000. Considering the actual selling prices and the listed prices, I estimated the market price by averaging the lower end of the selling prices and adjusting for the older model year.
