This week on The Best of Car Talk, Teddi's Camry screeches when she starts it. She's developed lots of techniques that seem to avoid the noise, but is she mistaking correlation for causation? Elsewhere, John's wife says he's triggering the Lardbutt Indicator in her Golf causing the horn to blare at random times, only when he's driving it. Also, mobile dog groomer Gwen needs to decide whether to repaint or replace her company van; Wendy's looking for a car she can work on herself to help her meet guys; and can Jeff use his camping stove fuel in his Civic in an emergency? All this and more, this week on The Best of Car Talk.
