No, I never seen any Bellett, Wasp or Bellett Express
Thanks to this forum, now I known about bellett and variants
Some people said that those Unicabs came into Indonesia when there's a big project funded by Japanese Goverment.
It ended in early 70's when some political issues came up and break this cooperation
Indonesia is occupied by Japanese during WW-II, so in 60's there is still a negative opinion about Japan and their product, including Isuzu.
Now there also a reason why Trooper and P'Up sold with Chevrolet badges in here.
