Here are a few I remember from my youth, in the '70s. I owned the 2-door coupe version of the Vauxhall and the Corolla, wish I'd owned all of the following in wagon form!
I don't know if these were ever sold in the US, but GM imported the Envoy Epic and its sister car, the Vauxhall Viva, into Canada from about the mid-'60s until about 1970. The next generation was renamed the Vauxhall Firenza, and was brought in for a couple of years. The Epic was sold by Chev-Olds-Cadillac dealers, and the Viva by Pontiac-Buick-GMC dealers.
Both cars did very poorly mechanically in Canada, to the point that the Epic was commonly referred to as the Epidemic. I owned an old beat-up '68 Viva, and testify as to its mechanical unreliability. Anyway, I thought the 2nd-gen wagon, shown, looked pretty slick back in the day:
The Japanese brands were very common in the western Canadian provinces of British Columbia and Alberta, with numerous dealerships springing up in the late '60s. I imagine the same was true of the Pacific coast states. Here are a few of my favourites from the day:
Datsun 510 wagon
Mazda 1200 wagon
Mazda 1500/1800 wagon
Toyota Corolla wagon
And finally, and bit later than the others, the amazing whale-like mid-'70s Toyota Crown wagon
These were available with a 2.6 l engine (a big 4, not an inline 6, if I recall correctly) and a 5-speed manual!
For whatever reason, I've always loved wagons.
