How cars can trap consumers in a mortgage mess

If you're a homeowner, go outside after dinner and count the cars parked in driveways, on the street and in garages. Divide that number by the number of households on your walk. Got a number close to two, or more? You've got a situation ripe for foreclosure, according to a statistical analysis conducted by the National Resources Defense Council. What's more, car ownership is a key factor in predicting foreclosure; more useful than average credit scores, income or a host of demographic factors, the NRDC concludes.
