Oddly optioned cars and Dealership demonstators?

I also had a '72 Duster that was a base car other than it had a 3 speed manual on the floor.
We're talking the only option it had was the floor shift.
198, manual steering and brakes, no radio, rubber mat on the floor, bench seat, standard outside mirror, steel wheels with pie plate hubcaps, etc etc.
It did have a heater, but in in Canada at least, it was standard equipment.
