I think it was in BNDEP as part of 'on test' purpose or just
went there to park. I definitely saw 3167J 3181S & 3188Z parked
together in the laid-up area on that day I posted though. But yeah,
seems like its under BBDEP now.
Talking about this, i remembered that there was 1 27 bc told me
that some sv27 buses,SBS8320A went to BNDEP for repairs
as well.
