To estimate the price of the 2017 Ford Fusion Titanium I4 2.0L Turbocharged with 221000 km mileage, I first looked at the selling prices of similar cars. The 2015 Ford Fusion I4 2.5L with 73700 km sold for 48000 SAR, the 2016 Ford Fusion I4 2.5L with 235000 km sold for 30000 SAR, and the 2015 Ford Fusion I4 2.5L with 186000 km sold for 16000 SAR. These prices suggest a range between 16000 SAR and 48000 SAR, with higher mileage cars selling for less. Next, I considered the listed prices of similar cars. A 2017 Ford Fusion I4 2.0L Turbocharged with 190000 km was listed for 40000 SAR, and a 2017 Ford Fusion I4 2.5L with 174000 km was listed for 31500 SAR. Given the higher trim and turbocharged engine of the target car, it should be valued higher than the base models. Considering the average condition and higher mileage, I adjusted the price downwards from the listed prices. Therefore, I estimated the market price to be 32000 SAR.
