FRANKFURT (Reuters) –
The German states that are home to General Motors (GM.UL) unit Opel's factories still prefer Magna's (MGa.TO) offer for the German company over the one made by RHJ International (RHJI.BR), several people familiar with the matter said on Wednesday.

The states of Rhineland-Palatinate, Hesse, North Rhine-Westphalia and Thuringia discussed the matter in a telephone conference on Wednesday, two sources said.
