This week on Car Talk, Lisa's husband's found a sure-fire way to curb her enthusiasm for a new Prius: he told her she has to clean the bird poop off it every 24 hours, lest it do permanent damage. Is he full of wisdom, or . . .? Meanwhile, Dale's spark plug wires are trying to escape; Cliff's key refuses to exit the ignition; and will Hope sell her car before she runs out of brain cells from that cracked exhaust manifold? Also, when Amy's Skylark is a-rockin', feel free to come a-knockin'--especially if you know how to fix a broken dog-bone. All this, plus a Puzzler from the Coins series, and lots more, this week on Car Talk.
