I started by examining the selling prices of similar cars. The most relevant data point is the 2015 Ford EcoSport 1.5 i4 Ambiente (Base) with 198700 km sold for AED 18500 on 2023-05-09 and 2023-05-05. These are the same variant and similar condition as the target car. The selling price of the Trend (Mid) variant with 152000 km was AED 18000 on 2023-10-29, which is slightly lower than the Ambiente (Base) variant, indicating the base variant might hold slightly more value. The accepted offers for the Trend (Mid) variant were AED 21000 and AED 18000, suggesting a market range. The listed prices for Ambiente (Base) variants were AED 21000 and AED 15500, but these are typically higher than actual selling prices. Considering the target car's higher mileage of 177400 km compared to the sold Ambiente (Base) cars, I adjusted the estimate slightly lower than AED 18500 to account for the additional mileage.
