This week on The Best of Car Talk, Tom and Ray have been called lots of things we can’t repeat in polite company, but they’ve never been more flummoxed than by high school student Lydia’s insistence on calling them “Sir." Is Lydia too polite to find out why the key keeps falling out of her car while she’s driving? Elsewhere, Suzanne is concerned about the gas fumes emanating from the “other woman” in her husband’s life, his Ford Model A, named Tootsie. Also, Faith’s trusty Subaru has become a little less reliable since she drove it from Maine to Alaska; Romeo had a lot of fun peeling out in his Olds Cutlass, but will he still be laughing when he sees the repair bill; and a quick quiz to find out if you could have a future in the exciting world of car repair. All this and more, this week on The Best of Car Talk.
