This a CBU (Completely Built Up) bus. That
means, the bus is produced as a complete package. SBS buses are different. Only the chassis is imported
from the manufacturer. Once the chassis have arrived, they would
start on the bodywork, which was bought as a knock-down package.
Imagine a model airplane set for example, with parts you need to
assemble together. Its exactly the same concept. SBS bus assembly line is in HG and it is quite
ordinary.
