Back when Mustangs were first introduced, 1963, Ford had plans for a station wagon version.

I knew two people from my HS years that owned 1965 Pontiac Tempest wagons. They were cool!
I preferred the first few years of the Cougar.
About 15 years ago, I had a 67 base model. It wound up being sacrificed to keep the peace and solve a problem or two.
The spouse didn’t care for the car.
I’ve told her that I will get another one someday and it will stay.
