Many MGA were shipped around the world in the form of Completely Knocked Down units to be assembled in other countries. The total content of these "kits" would depend on the resources of the assembler at the destination. Wheels and tires and batteries might not be included, and the car bodies were generally not painted prior to shipping (except for primer). Here we have some links to information about these cars. Some of this is off site, in which case the links will be as good as the longevity of the referenced web pages.
