I have a couple to add.
Krause Brothers Chrysler /Plymouth on Schaefer and Puritan
Also there was a dealership in Mcnichols, just west of Schaefer it was a Kaiser Fraser dealership then it became a Studebaker dealership then it turned into a sports trophy saleroom. Can't remember the two names of the dealers though?? Maybe someone can come up with the names??
Coon Brothers Nash on Telegraph and Plymouth
Gene Merollis Chevy , I think was on Joy Rd. west of Southfield. Great commercial
