i think there is agent... a lot of pte bus operators using yutong.
it's one of the best china bus brands, can be considered a world
class brand, seriously. another one is king long.
between the both i feel king long is better.
price wise, im not sure whats teh difference between buses from
YT and KL, say both are given with the same specs (engine power,
length, etc). but so far my experience with kinglong coaches has
been good. engine noise is well insulated, the air con is good, the
seats are italian FAINSA, and there are even LCD tv's in the bus.
keep it up, king long :)
