Anyone seen a little item called, very descriptively, Hot Cars (1956)? Quite a lot of fun. John Bromfield makes a convincing used car salesman; the racket he gets involved in is credible; the Los Angeles locations are fabulous, including Jack’s at the Beach in Santa Monica; and the climactic sequence is pretty sensational for an hour-long low-budget picture.
