Troubling new trend in auto loans

CBS News financial analyst Mellody Hobson reports that stretch-loans -- loans paid back over a long period of time and popularized during the Great Recession -- come with a huge downside.

The average loan now lasts more than five years. Hobson warns that paying for your car over such a long period renders them like homes, which can end up "underwater." Over the years, not only will you end up paying more in interest, you wind up with a car worth less than the payment you're making.
