Most of the Korean and Japanese car agents remove the airbags
for shipment to singapore.
So those NCAP rating does not apply to them anymore.
Even they get 4 to 5 stars in NCAP, it is usually done with maximum
airbags and safety feature. This assumption will not hold if they
remove the items and bring it to singapore.
That is also why they don't dare to claim NCAP rating for their
model.
