Or maybe they have a family with kids, they live in an expensive part of town, but moving is not an option due to job constraints, or maybe the kids are going to school there and moving would be disruptive. Maybe that area didn't use to be so expensive 10 years ago. They need cars, not 80k cars, but large enough to haul said family around, cause maybe public transportation sucks where they live. Heck, maybe they bought those cars in cash, no payments, but gas, insurance & maintenance (maybe they're old cars) are killing them. Car prices are too expensive to get a new car, so they keep spending 1000s in repairs instead. Maybe a hurricane, strong winds or just normal wear and tear made their house roof leak, thats $20k right there, ask me how I know.

Also, a 600k house is cheap and almost impossible to find in California, for example. No, moving to Texas is not an option, thanks.

Edit: the example above is hypothetical, not my current situation, but based on my experience.
