To estimate the price of the 2017 Ford Taurus I4 2.0L EcoBoost Ambient, I first considered the selling prices of similar cars. The most relevant data point is the 2019 Ford Taurus I4 2.0L with 169,000 km sold for 55,500 SAR in January 2024. This car is newer but has similar mileage and condition. The 2015 Taurus SEL V6 with 72,000 km sold for 46,500 SAR in September 2023, but it has a different engine and lower mileage. The 2015 Taurus V6 SE with 162,000 km sold for 47,000 SAR in July 2024, which is closer in condition and mileage. The listed price for a similar 2017 Taurus I4 2.0L was 45,000 SAR, but it was delisted, indicating it might not have sold at that price. Considering these factors, the 2017 model's price should be slightly lower than the 2019 model due to age and higher mileage, but higher than the 2015 models due to being newer.
