To estimate the price of the 2017 Chevrolet Silverado V6 4.3L Trail Boss (Mid+), I first considered the selling price of a similar 2017 Chevrolet Silverado V6 4.3L with 98900 km mileage, which sold for SAR 63000 on 2024-05-18. This car was in average condition and a base variant (V6 WT). Given that the target car is a higher trim (Trail Boss) and has higher mileage (199000 km), I adjusted the price downwards. Next, I looked at the listed price of a similar 2017 Chevrolet Silverado V6 4.3L Trail Boss with the same mileage, which was SAR 66000. Considering that listed prices are generally higher than selling prices, I adjusted this downwards as well. Finally, I reviewed other listed prices of similar cars, such as a 2018 Trail Boss with 214000 km listed for SAR 65000, and a 2017 Turbo LT with 114400 km listed for SAR 51000. Taking into account the higher mileage and the fact that the car is in good condition, I estimated the market price accordingly.
