Lets preserve everything... the list is too long, hor?...
Personally I like the Volgren Merc of SMRT as well, especially
TIB966X, very good bus...
I don't really know about the Scanias and their emmisions though,
but all buses seem cool to me too...
LTA does not support mobile home licenses, partly because Singapore
is too small, but I do have dreamt about driving a modified Volgren
Merc across Asia continent, to be the first person driving a 12m
city bus to Europe etc, quite complicated though, people have done
it with vans, bicycles, motorcycles, trucks, cars, tuk-tuks
(Finnish man), why not with a bus?
