It must have been fun to live in the 1930s, when everyone had a brand-new car, no matter their occupation or social station. At least, that’s what you would be led to believe watching period films, like The Untouchables or, apparently, the new Public Enemies. I realize these old cars are antiques now, but some period movies seem to make a fetish of verisimilitude, yet depict every vehicle as gleaming and in pristine condition. Look, this isn’t like Carl Carlson on that “Simpsons” episode asking, “How come oldies stations are always playing the same song? How bout some NEW oldies, geniuses!” Cars made back then are actually old now. Dig one out of a junkyard and park it somewhere in the movie. Other than “O Brother, Where Art Thou, I’m having a hard time coming up with a movie that had period jalopies. I guess they don’t give out Oscars for finding junkers.
