I daresay Boon Lay has probably the worst buses. The Int full of
Merc, Mk2s, VO2x, and LO3x with a few VO3x from svc 198, 154, and
30.
I think you should also stay away from Toa Payoh, Ang Mo Kio,
Bishan also, they have tons of LO3x and Merz.
btw Scania no longer forms the backbone of svc 293, 358, 359
fleets, alot of them have been replaced by Mk3.
