Curious that this story of the Packard plant on East Grand Blvd. in Detroit and the Packard Proving Ground out toward Utica are in a story posted under the Packard V-8 section. When in reality, neither of the places most directly connected to Packard V-8 automobiles (1955 and 1956) even exist today.
The engine and transmission plant at Utica is certainly gone. And more importantly, the place where all the final assembly lines were at Conner Avenue is long gone too! I don't know of a single tour or lecture or history today that even has more than a passing mention (if that) of either of these two important sites.
It is also interesting that the history of the Packard Plant on East Grand Boulevard is being attributed to the present owner (who apparently has renamed his business from "Arte Express" to "Packard Plant Project"?). As if that operation is a keeper of said history, despite other sources with far more history, knowledge and images... and longer involvement. And what happened to the apartments (including one for the new owner) and businesses that were supposed to be up and running there by now? Apparently there is no more express in the "arte"...
So. Despite the millions upon millions that were spent building and creating the Utica plant and the Conner Avenue plant (which at the time of their demise were two of the most modern production plants in the world), there is no mention. The real history here for V-8 Packards is still lost, no matter how much we talk about the other two sites.
