1971 Datsun 240Z Commercial - “A New Kind of Economy Car“

I never knew the 240z was an Economy Car, but then again, I do remember my Dad shopping for an Economy Car in 1968, looking at everything from AMC Rambler Americans to Renaults, he decided on the Datsun my Mom changed his mind and he got the Datsun 1600, so I guess, maybe sports cars were also considered Economy cars too.
