This week on Car Talk, Tac and her siblings are looking for a way to keep their dearly departed dad's car in their memories, but out of their wallets. So before they bid farewell to his Camry, she's wondering what parts work best as keepsakes. Maybe a tire to hang on the wall? Elsewhere, Anne is longing to buy a vintage MG convertible, but her husband's insisting it come with one accessory - an English mechanic in the trunk. Also, our resident Chemist Jim Davis follows up on the hazards of urine in a radiator; the men of Maple Corner try to keep their parade car from bursting into flames; and can Chris's carburetor problems be solved by a run through the dishwasher? All this and lots more, this week on Car Talk.
