SBST can consider extending SBS978E, felt the condition of the
bus is still good after taking a few times on Sv 153. Currently,
the bus has not been refurbished yet...
For SBS990T, it has differential gear problem when I last took it
where it would produce weird sound when the bus starts to
accelerate...
Felt that SBS984L is still alright, haha. Last time when it was
on 153, the condition was quite bad but have rectified the
problem...
