This week on The Best of Car Talk, can Cathy drive her dog 2,000 miles to summer camp in a truck without AC, or should she spend big bucks to cool all involved? Elsewhere, Dorothea’s dealer changed her belts, and now her car is shrieking. Does she need a big lawyer, or a big stick? Also, Richie’s dual oil system proves the adage, “The stingy man spends the most.”; Tom and Ray ponder whether members of the Witness Protection Program get to hang out with each other; and did you know William Shakespeare was Italian? All this and more, this week on The Best of Car Talk.
