This week on The Best of Car Talk, Carol needs help refereeing a family argument over a car question in the game Brain Quest and charter "Densa" members Tom and Ray show her she came to the exact wrong place. Elsewhere, Dr. Ron is hoping to prove to his wife that he's not the one killing their clutches. Fortunately for him, there may be another suspect available. Also, Bob's Volvo seems to have more power after bending the exhaust during a game of Driveway Tag; a valet used Kenneth's Dodge key to start Kenneth's Subaru and Lisa is relying on a piece of wood jammed into the ignition to keep her Moskvitch running. All this and more, this week on The Best of Car Talk.
