In this week’s Car Talk, Joel’s mechanics tried to flim-flam the wrong guy. Someone sealed a few shop rags into the transmission of his Blazer - but nobody’s owning up. Does he smell a lawsuit? Tom and Ray help settle Crissy’s bets with her friends. A listener compares “stump the chumps” to a session of the U.S. Supreme Court. Is Darth Vader living in Marilyn’s air conditioner? What’s with the creepy fog pouring out of the air vents? That, the long-awaited return of the puzzler and much more, in this week’s show.
