My first reaction to the news about Renault, Nissan and General Motors was, 'Has Ghosn started to believe his publicity?' Sure, it must have been flattering to be asked to lunch with Kirk Kerkorian and Jerry York, men who have made a substantial living, thank you, from their plunges into the shareholdings of major motor companies. Even a man whose ego is massaged as devotedly and often as Carlos Ghosn's would find that an intriguing concept, writes Karl Ludvigsen.
