At its peak, BLMC owned almost forty manufacturing plants across the country. Even before the merger, BMH had included theoretically competing marques that were in fact selling substantially similar badge engineered cars. The British Motor Corporation had never properly integrated either the dealer networks or the production facilities of Austin and Morris. This had been done partly to appease poor industrial relations – workers at Cowley for example still perceived themselves as "Morris" employees and still, therefore they refused to assemble cars badged as Austins, and the converse was true at the former Austin plant at Longbridge. The upshot was that both plants were producing badge engineered models of otherwise identical cars so that each network would have a product to sell. This meant that Austin and Morris still, to an extent, competed with each other and meant that each product was saddled with effectively twice the logistics, marketing and distribution costs that it would have if sold under a single name or if production of a single model platform was concentrated in one factory. Although BL "did" eventually end the wasteful double sourcing – for example production of the Mini and the 1100/1300 was concentrated at Longbridge, whilst the 1800 and Austin Maxi ranges moved to Cowley, the production of sub-assemblies as well as component suppliers were scattered all over the Midlands which greatly increased the cost of keeping the factories running.
