I think that is debatable. Sure, BMW could target young Asian kids with rich parents on facebook, but there's already a rather big demographic targetting with the likes of Youtube and Google's data on a user.

Facebook would be great for someone showing off their purchase not necessarily for buying products through poorly placed ads that your brain is trained to ignore.
