I started by looking at the selling prices of similar used cars. The closest match is the 2014 Ford Mustang 3.7L V6 Premium (Mid) with 171000 km mileage, sold for AED 34000 on 2024-03-27. Given that the target car is a 2013 model with higher mileage (248100 km), I adjusted the price downwards. Another relevant data point is the 2013 Ford Mustang GT 5.0L V8 with 211000 km, sold for AED 24000 on 2023-11-19. Although this car has a more powerful engine, its lower price suggests a significant depreciation due to mileage and age. The listed price of a similar 2013 Ford Mustang V6 3.7L Premium (Mid) with the same mileage is AED 23000, which is likely higher than the actual selling price. Considering these factors, I estimated the market price by weighing the selling prices and the listed price, adjusting for the higher mileage and the car's condition.
