Packard has
a history beggining in Warren Ohio. The museum and annual show is there.
After Henry B. Joy bought most of the company's stock, it moved to Detroit.
General Motors named the electrical division in Warren Ohio Packard Electric.
They used to make every wiring harness for every GM vehicle.
Packard had a large proving ground and lodge in Shelby township Mi. They spent way too much money designing their own automatic transmission, while Ford bought their first from Borg Warner, and were even using GM Hydramatics in Lincolns.
Richard Teague designed that beautifull Packard Patrician above, then went to American Motors upon the merger of Packard and Studebaker, also a failing company.
Hudson and Nash merged to be the number four automaker AMC.
With Mercury, Pontiacs, Oldsmobiles, and Buicks nearly as nice as a Packard, with lower price tags, they just couldn't compete with that. I think even a base level Cadillac costed less. Production ended with the 1956 model year. The factory is finally being demolished, what hasn't fallen down on it's own.
