The typical value of a used 2008 Chevy Silverado is about $19,500, based on Kelley Blue Book estimates as of July 2015. The vehicle's trim level, optional features, condition, mileage and location can impact the value.
In fair condition, a 2008 Chevrolet Silverado 1500 Crew Cab LT pickup in need of some mechanical and cosmetic repairs may sell for around $14,500 through a private party sale. In the same type of private transaction, a Silverado 3500 HD Extended Cab in excellent condition could fetch $24,399.
Low mileage and high-end options often increase a truck's sale price, while high mileage, mechanical defects and cosmetic problems reduce the final price.
