This week on Car Talk, Click and Clack fork over a unique diet not to be missed. Spoiler alert.... you're not actually allowed to eat! Then it's off to help Doctor Gary with an ethical conundrum. If he gives his mechanic car advice, can the mechanic start giving Gary medical tips? Carole wants to know what kind of car she should take to Africa, and has an automotive-fashion question: should she stock up on jog bras for the rough roads ahead? And in Phoenix, Caesar gets some help with his love life. All that, plus a spine-tingling puzzler, this week on Car Talk.
