Photos of Completed 1979 Dodge Magnum Build. Model completed 3-23-08. See the build photos here in these posts. Many years ago, before the Dodge Magnum was introduced as a station wagon, it was a sport coupe. These sport coupes were produced only during 1978 and 1979, and they were based on the 1975-79 Chrysler Cordoba body shells. 1979 Dodge Magnum sport coupe body-in-progress, along with an earlier photo of the interior. This model is based on a Magnum I saw in a dealer's showroom in 1979.
