To estimate the price of the 2016 Ford Focus I4 1.5L EcoBoost Ambiente (Base) sedan with 205800 km mileage in bad condition, I considered several data points. First, I looked at the selling prices of similar cars: a 2016 Ford Focus 1.5L i4 hatchback with 172800 km sold for AED 20000 on 2024-02-18, a 2016 Ford Focus 1.5L I4 sedan with 200000 km sold for AED 13500 on 2023-09-03, and a 2016 Ford Focus 1.6L I4 hatchback with 224600 km sold for AED 10500 on 2024-05-31. The closest match in terms of body type and mileage is the sedan sold for AED 13500. Considering the bad condition of the target car, I adjusted the price downwards. I also reviewed listed prices: a 2016 Ford Focus 1.5L I4 sedan with 177500 km was listed for AED 16000, and a 2016 Ford Focus 1.5L i4 hatchback with 172800 km was listed for AED 18000. These listings are higher than actual selling prices, so I used them as upper bounds. Finally, I considered an offer accepted for a 2016 Ford Focus 1.5L EcoBoost sedan with 166000 km at AED 22000 on 2023-09-17, which is higher due to better condition and lower mileage. Based on these data points, I estimated the market price for the target car.
