A traffic sign is seen in front of the headquarters of German car manufacturer Opel in Ruesselsheim November 4, 2009. German and Russian leaders seethed and unions tore up a deal to cut costs in protest at General Motors' "completely unacceptable" decision to keep Opel, its European unit, after months of sale talks. Labour leader Klaus Franz rescinded hundreds of millions of euros in cost concessions that workers agreed to on condition that Opel was bought by Magna, the Russian-bascked Canadian group long backed as buyer by Berlin and Moscow.
