Another interesting thing about the "Suburban" name is that several manufacturers used it, too, during the same period. Plymouth used it to denote wagons in several different models up to 1978, which was the last full-sized wagons from Mopar. Hudson and Studebaker each used the name for one or two years each.

Cadillac was actually the first to use the name, in the 'teens. GMC/Chevrolet have used it continuously for over 70 years, as Stan noted.
