Believe against copyright law. However, would BMW really care?
Also, I think there was a link, check archives, to a european site that has PDF versions of many many brochures. I am trying to collect as many different USA e34 brochures as I can find. I found a great europeran 94/95 (?) e34 M5 brochure on ebay.
I also have an interest in original e28 and 1600-2002 brochures having owned both these cars.
Thanks,
