I started by examining the selling prices of similar cars. The 2014 Ford F150 5.0L V8 with average condition and similar mileage sold for AED 50,000 on 13 Sep 2023, AED 37,000 on 5 Feb 2024, and AED 63,000 on 22 Jul 2023. The accepted offer for a similar car was AED 51,000 on 13 Sep 2023. These prices suggest a range between AED 37,000 and AED 63,000, with a more recent sale at AED 37,000. The listed prices for similar cars range from AED 36,500 to AED 54,000, with a relevant listing at AED 45,000 delisted on 6 Feb 2024. Considering the car's mileage of 178,000 km, which is higher than some of the sold cars, and the average condition, I estimate the market price to be closer to the lower end of the recent sales, around AED 40,000.
