Dodge, a division of Chrysler, has a long history of producing performance-oriented vehicles with a distinctive American character.

Model Evolution:

The Dodge Magnum was reintroduced for the 2005 model year, based on the new LX platform shared with the Chrysler 300 and Dodge Charger. The 2004 model year is a unique iteration before the full LX platform rollout, representing a distinct period in Dodge's product strategy.

Production Years:

This manual specifically covers the 2004 model year, which may have had a limited production run or represented a pre-production/early launch variant of the LX platform, or it could be a mislabeling and the manual actually covers the 2005-2008 generation. Assuming the title is accurate, it refers to a 2004 model on the LX platform.

Manufacturing Location:

Brampton Assembly Plant, Ontario, Canada.

🏆 Awards & Recognition

Recognitions:

While the 2005-2008 generation of the Magnum received critical acclaim for its performance and styling, the 2004 model may not have specific awards associated with it as it represents an early iteration or transition.
