Recession in a Lexus

This story on Andrew Sullivan's site about a homeless family bathing their young children at an Orange County gas station is heartbreaking.  A curious detail is that they were driving "a nice sedan - maybe a Lexus."  

If it was indeed a Lexus, does the car speak to years of one family's overspending and undersaving leading to this terrible situation?  We'll never know, but the irony of finding a homeless family in a Lexus is stark.
