This week on The Best of Car Talk, Penny bought her ex-husband's third wife's old Volvo. If that sounds complicated, wait until you hear everything Penny's done to try to figure out why the car is overheating. Elsewhere, Scott's Festiva died after driving through a deep puddle and Scott's friend is trying to convince him his tailpipe managed to suck water and blow out exhaust at the same time. Also, Chandler is pondering a life without hubcaps after hers were stolen; Mike is looking for the right car to help his uncle get his kicks on Route 66; and Kathy needs help navigating the mind of the modern mechanic, who happens to be her husband. And, on Stump the Chumps, did Ellen finally find a way to distract her husband from the JC Whitney catalogue? All this and more, this week on the Best of Car Talk.
