I need historical and projected sales (in unit terms).  I need to know
the size of the addressable market for OEMs (i.e. GM, Ford, Chrysler,
Toyota, Nissan, BMW, etc) as well as trends within the aftermarket
sector, now and in the future.  It would be particularly helpful to
know the size, finish (i.e. polished, chrome, cladded, painted, etc)
specifications that OEMs are designing into new model platforms, and
the expected future trends in the same.  I also need a breakdown of
production by the type of technology used (i.e. forged, cast, etc.). 
In addition to any data you specifically provide, I would also be
interested in references to other market research which I could
purchase to supplement my research.
