… after just one year of ownership by Peugeot/Citroen.
When you consider that GM wasn’t able to wring even 2 cents of profit out of their Opel division for almost 20 years, I think that Opel’s new French ownership/management is quite impressive.
Or GM’s financial and management burdens were quite oppressive ! 
Good for Opel and Vauxhall.
GM divisions sold off have done pretty well. Except Delphi - Too large and too much GM inbreeding for Delphi to be successful!
