Plymouth built well over 120,000 Suburban wagons for 1959, split across Deluxe, Custom, and Sport trims, with the mid-range Custom alone accounting for 53,869 units. They rode a wagon-specific 122-inch wheelbase with torsion-bar front suspension, came standard with a 132-horsepower flathead six, and could be ordered with a 305-horsepower Golden Commando V8. Almost none survived, because families used them up. Read on for what made the Big Fin wagons worth a second look.
