I had searched about some informations about buses, when refer to the google, i had find some news report about malaysia public bus.
I am not pointing out who is right and wrong but just express that maybe there were quite a big waste to change such a large number of old buses.
hope you interest.
To be honest, the condition of those buses are terrible and old. (You should know how terrible the condition they are during their life time spending in Intrakota and Cityliner.) It is really not worth to do any more refubrishment. It is time to scrap them and replaced by new buses from China.
