I'm under the impression that the 1930 Cadillac can be somewhat under-powered with the V8 engine. Can anyone share their experience with me. What is a comfortable, prudent cruising speed? What is the approximate full speed? What is the standard differential ratio? I am interested in purchasing a car mostly for occasional, local driving enjoyment. A cruising speed of fifty mph would be fine. However, participating in a regional rally or travel to a regional meet is of interest. I don't believe that I need particularly high speeds, but occasionally it is most convenient to be on a highway where fifty-five or sixty mph speed is appropriate. Will I find a 1930 Cadillac V8 suitable for my purposes? I appreciate your input. Steve
