Also useless to Nissan, Tata Motors, Hyundai Magna and GM
I'm not saying that it was a bad deal for Fiat ..far from it. But just becuase it was a good deal and gets Fiat into the market for basically nothing doesn't mean that Chrysler as an overall company is going to be sucessful. Its a great deal for FIat to get a foothold in NA. The government is giving out BILLIONS in handouts that they don't expect will be rapaid.
If the goal was free government money, instead of a mutually-beneficial long-term relationship with Chrysler (a la VW and Skoda), everyone would have been scrambling to get Chrysler. But it's NOT free government money. The US bailout is low-interest loans, not free money.
The other companies on the list weren't in a situation to make a good business working with Chrysler. GM and Nissan and Hyundai already have solid footholds in North America, so they're in the same boat as VW. They wouldn't get what Fiat gets out of the deal.
As for Magna, maybe they just wanted to stay in the parts business and not sell cars. Maybe, like many parts makers right now, they're having cash flow problems and didn't think it was time to expand the business. Can't read too much into that.
Tata is in a similar boat to Fiat in that they don't have a foothold in the mainstream North American car market yet. But remember they just bought Jaguar and Land Rover, arguably more troubled than Chrysler, and are probably pumping all the spare capital they have into turning around those brands before trying to acquire any more.
Edit: As a side note regarding your signature, it's Aldous, not Aldos.
