Really true 
Oso found out tat most of the buses esp the older batch of MB0405s
and Scanias r very dirty: the floorboards got lots of stain marks,
plastic on the back of every seat full of dirt marks, armrest on
window dirty n stain marks too, aircon ducts oso found full of dust
CAC nissans r much more horrible......some aircon not cold enough
esp in d hot noon, rattling on gaps btw window panes, oso got lots
of debris too, seats very dirty, bus suspension very horrible,
worse till coc-k-roach on d bus
Whenever I see a coc-k-roach then will think of "Kan Jian Zang Lang Wo Bu Pa Bu Pa La"
tat song sung by Guo mei Mei 
At least SBST buses r much cleaner nowadays, refurbished new seats,
clean aircon ducts n floorboards, clean window armrests too
I think SMRT shld oso be more concerned wif personal hygiene n bus
cleaniness too
