I vote 7335P as the noisiest bus in SBST.
Anyone can try to top this bus with another candidate?
I have the ill-luck of having to hear this demon at least 6-7
times a day if I'm at home.
It's so damn loud you hear it before you even see it within the
next 15 seconds before the bus appears from behind the buildings
and trees.
As for vibrations...not much better than the K230UBs. My brains
get rattled so much it becomes meaningless to compare the KUBs,
B9TLs and the Hino Volgrens.
Edit to add: If you have the ill-luck of having to sit at the
bus-stop when 7335P starts reving up its engine, your ears can be
assured to melt.
