Here in Wisconsin First Student usually orders stripped down bare bones IC buses with nooothing on them whatsoever - leaf spring rear suspension, hydraulic brakes, only one driver fan. They don't even come with heated mirrors
They then run them into the ground and dump them at auctions when there's absolutely no life left in them.
In a few years the used bus market will be flooded with the newer style IC busses with those awful Maxxforce engines. They will be complete and utter lemons without exception.
