Old Car Dealers in the Detroit Area

[RGK20m3]

Norwest Dodge does sound familiar for that location….

Northwest Auto Co. was an import dealership selling MG and Austin Healy at that address per a recent thread on this site titled British Car Dealers; perhaps they got a Dodge franchise prior or after?
When I worked there I recall it being very small for a domestic brand, but would have been fine for MG/AH.
