Why you can never buy a decent used car. By Tim Harford

and so we come to Tim Harford who neither illuminates some little facet of everyday life nor offers a view on some major moral issue. In fact, he doesn't even make much of an economic point -- he just sort of diddles around on the periphery. He's just convinced you that there's something interesting to think about and getting you ready for something interesting when he thinks he's done.
