A bid from Belgian investment company RHJ International SA (RHJI.BT) for General Motors Corp.'s (GM) Adam Opel GmbH European unit would require only EUR3.8 billion in government financing guarantees, compared with the EUR4.5 billion of Magna International Inc. (MGA), a person close to the matter told Dow Jones Newswires Monday.

RHJ International wouldn't close any Opel plants in Germany or England, the person said. The Brussels-based company said earlier Monday it is in advanced talks with GM to acquire a stake in Opel.
