Forget about the Hummel figurines and Slim Whitman CD collection, this week's encore edition of Car Talk tackles one of the most serious of break-up questions: When love flies out the door, who gets to keep the mechanic? And, would an endorsement from Tom and Ray help or hurt? Elsewhere on the relationship front, should a wife support her husband in an activity that could well acquaint him with the ER? Also, a tale of two trucks: one sends our hosts into Duck and Cover mode, the other into a full-blown existential crisis. And on Stump the Chumps, our contestant is...our very own co-host, Tom? Find out how his big mouth put him on the spot-- again. All this, plus a few follow-up thoughts on the fabled Andy Letter, this week on Car Talk.
