It was no secret why Italian automaker Fiat (NASDAQOTH: FIATY) wanted Chrysler when nobody else did in 2009: Even in bankruptcy, Chrysler's size and resources had the potential to transform regional player Fiat into a global contender.

That bet has paid off: Chrysler is solidly profitable now, and its products are surprisingly competitive. But while Fiat was nursing Chrysler back to health, it was losing ground at home to Volkswagen (VWAGY -1.11%), Ford (F 0.69%), and other rivals.
