I started by looking at the selling prices of similar cars. The first car, a 2016 Ford Focus 1.5L I4 hatchback with 172800 km, sold for AED 20000 on 2024-02-18. The second car, a 2016 Ford Focus 1.5L I4 sedan with 200000 km, sold for AED 13500 on 2023-09-03. The third car, a 2016 Ford Focus 1.6L I4 hatchback with 224600 km, sold for AED 10500 on 2024-05-31. Given that the car to be estimated is a 2016 Ford Focus 1.6L I4 hatchback with 217000 km, I considered the first and third cars as the most relevant. The first car sold for AED 20000 but has a smaller engine size, while the third car, which is closer in engine size and mileage, sold for AED 10500. I also looked at the listed prices: a similar car with the same mileage and specs is listed for AED 19500, but listed prices are generally higher than selling prices. Considering all these factors, I estimated the market price to be slightly lower than the average of the relevant selling prices.
