See, SBST so much better! My other non-bus enthusiast friends,
when they sit the SBST CAC buses, and I tell them the bus was once
NAC and SBST converted it, they will be surprised because the
interior still looks rather new and clean!
But for SMRT, so bloody obvious which were once NAC buses... They
never even bother to change the windows and on ELBOs, the windows
vibrate like hell.... Then the window sills very dirty because of
all the dirt collecting on grooves to let the window open...
