Reliability and Maintainability

A brand new Peterbilt 389 model costs less than $200,000, while a used one will cost approximately $130,000 for 2015 to 2020 manufacturing dates. 

Expect more affordable prices with older manufacturing dates.

The high price is reasonable, though.

While the truck has been around us since 2006, its features have also evolved. It is also now equipped with the same features available in newer Peterbilt models.

For instance, if the 2006 389 model uses Cummins engine, the 2021 model uses the PACCAR engines.
