Toyota's CamryToyota's CamryBy E. Thomas McClanahan, Kansas City Star Editorial Page columnist

Some people make a big deal out of buying American, but when it comes to cars, what does that mean? It's harder and harder to tell domestic from foreign, and Cars.com's American-made index shows why.

In the latest list, the Toyota Camry nudged out the Ford F150 pickup as the most American vehicle. In fact, Toyota had four models in the top 10.

Ford and GM together had five. Chrysler had none -- its popular minivan is made in Canada.

Unions make a fetish of only allowing American-made cars in certain lots at car plants. (The Carpe Diem site, where I found this item, has photos of a couple of typical warning signs.) Would the unions permit a Chrysler minivan but bar a Camry? How much sense would that make?

In a global economy, a lot of the stuff we use is made ... everywhere. One result is lower prices and greater access to good products for people of modest means. In hewing to outdated notions of "American made," unions are clinging to distinctions that are increasingly fuzzy.
