Abstract: A vehicle body consists of six independent body sections, i.e., an engine compartment assembly, floor assembly, rear end assembly, a pair of body side assemblies and roof assembly. The assemblies are prepared and painted independently and then respectively provided with equipment such as an engine, suspensions, upholsteries, etc. so as to constitute an engine compartment module, floor module, rear end module, body side modules and roof module, respectively. A complete vehicle or nearly complete vehicle is obtained by joining the modules together with bolts and nuts.
