This week on Car Talk, James thought he got a good deal when he bought his neighbor's Cadillac--and that's before the cash rebate, in the form of $3,200 hidden in the trunk. Should he hand the money over, or tear the rest of the car apart in search of more? Later, Tom and Ray are vexed by two noises: Scott thinks someone's playing a French horn under the hood of his Explorer, and Jane keeps checking her Civic's trunk for the passenger who's banging on the sides. Also, Barry's lived a car-free life into his 30's, but his relocation to L.A. has him wondering if it's time to give in. But will a car lead him directly to Botox injections? And our deep question of the week: do we really need a Click AND a Clack? And if not, which Magliozzi's moot? All this, and lots more, this week on Car Talk.
