To estimate the price of the 2019 Ford F150 V6 3.5L Twin Turbo Regular Cab XLT (Base+), I first looked at the selling prices of similar cars. The 2017 Ford F150 V6 3.5L EcoBoost Crew Cab Lariat (Mid+) with 101500 km sold for 138000 SAR on 2023-10-11, and another 2017 model with 215000 km sold for 55000 SAR on 2024-07-10. These prices suggest a wide range due to differences in mileage and condition. Next, I considered the listed prices of similar cars. A 2019 Ford F150 V6 3.5L Twin Turbo Regular Cab XLT (Base+) with the same mileage of 63000 km is listed for 123500 SAR. Other listings include a 2020 model with 101000 km listed for 143000 SAR and a 2018 model with 93000 km listed for 85000 SAR. Given the target car's average condition and mileage, I adjusted the estimate slightly below the listed price of the 2019 model to account for negotiation and market conditions.
