It has already been said there will be no new bus orders for a while, so that can only mean that the citaros will probably be in the fleet for some time unless newer vehicles can be sourced from elsewhere (pre loved ones) who knows what the plans are but im sure a plan is in place and the life expectancy of the citaros is being monitored, they wont last forever but they are solid buses and for their age what bus doesn't have issues, they are still pretty reliable
