This week on The Best of Car Talk, Fran and her boyfriend are both jocks, and as a result, her Taurus smells like a locker room. Will a few dozen Odor Eaters hanging from the rear view mirror get rid of the stink? Elsewhere, Margo’s dad gave her his Cadillac, but her noisy brakes have Tom and Ray convinced Dad may be trying to bump Margo off; Matt wants to cure his wife of her habitual door slamming; Drew can’t decide if his shuddering engine really is a problem, or if he’s a moron; and, “Martha” bought a used van from a dealer six months ago, but has yet to be billed or pay a single cent for it. Should she keep quiet, fess up, or trade it in for a new one? All this and more, this week on The Best of Car Talk.
