EARLY 28Z
A major design shift from the earlier ordinaries which had smaller box windows , the last panel of the sleeve of these ordinaries were a bit sloping . These continued the old green/cream color interiors and had a single seat facing opposite side behind the rear door .
MID 28Z
These look same as the earlier ones apart from the last panel which was made straight . These were introduced along with the second generation metro express with middle door .
LATER 28Z
These were the last of ordinaries registered as "28Z" and had a major design shift . These were the first ordinaries to feature stick on glass over the window panes and the earlier box type windows with aluminium frames were replaced with glass only panes which are in wide use now . These have a gasket (?) on one pane to stop rain water entering inside . Also, the single seat behind the rear door was removed from this model . these had rear split wind shield at rear too .
