Unique translucent articulator concertina that allows sunlight
to illuminate turntable of SMB388S MAN NG363F A24 "MANDY"!
150 More MANDY buses will be coming up in the future! :)
Info from BIS number one page on Singapore Buses~

Really is 150? I checked with BIS, he told me this. " not sure
leh, but i'd say when MK I leaves it's likely the same number of MK
I replacements will appear "
No proof, don't say. 
IMPORTANT!
Users, don't read BIS information updated by 'SMB388S'. All
official BIS information are on facebook. Because everytime you
read 'SMB388S's ' information, you just got trolled.
