The difficult task ahead for Fiat's Marchionne, trying to reverse Chrysler's decline. Running Opel and Fiat, will take a lot of energy and initiative, and its by no means clear how he is going to go about doing this. Some arithmetic done by analysts shows the value of the Fiat, Opel, Chrysler auto companies, by excluding other non-auto parts of Fiat, and taking out Fiat debt and liabilities estimated at $8 billion euros. And taking that number and Fiat's market cap, the difference gives a value of 5.5 billion euros as what investors ascribe to Fiat Auto and its ambitions. This is just one fourth of the Fiat auto units 2009 revenues of 21.7 billion euros, as estimated by Morgan Stanley.
