The Leyland Atlantean and Olympians seem to be a popular choice.
Did anyone have a particular type of model or body that was a favourite?

I can't remember the model or who the coachbuilder was - but one of the Gateshead Atlanteans stood out, only because it had a giant black bumper at the front of the bus.
As far as I'm aware, it was the only type of its kind in the area and because it was unique and different, I loved it.
