I dont think BMW make many of the parts. As the others have said the engine and chassis is probably built by BMW. I'm pretty sure even the electronics are manufactured by suppliers as this is what most major manufacturers do. My wife works for Jaguar Land Rover and she tells me most of the parts are manufactured and supplied by others. There are loads of big suppliers Valeo, Bosch, Prodrive, TRW etc who design and manufacture systems for most of the major automotive firms.
