If it’s good enough for Hemmings to call it a wagon, and they were billed as wagons in Chrysler’s brochures, who am I to argue. I still use my definition, regardless of tailgate, or back opening apparatus.... if the car was made as a coupe or sedan, and had a longer roof, with a load floor vs trunk, and model resemblence, also used for multiple applications ie hauling passengers in seats or cargo with seats down, and clear through opening in the cabin, it’s kinda a wagon, 99.4% of the time. The other .06% I don’t care about, or they miss use the wagon monicker.
