This week on Car Talk, brace yourself for a call that's destined for our Car Talk Hall of Fame. The star is one kindly 82-year-old named Lily, from Indiana. The question: will Tom and Ray play Santa? Lily's ready to dump her '90 Cutlass. But should she - and if she does, should her son and grandson cough up the dough? In true Car Talk fashion, there's only one way to resolve this inter-generational, intra-familial conundrum: pick up the phone! Listen in as the next generation chimes in - and comes agonizingly close to massive embarrassment in front of a few million listeners. It's our Call of the Week, and one we'll be talking about for quite some time. Meanwhile, in other family matters, what makes a smart kid do a dumb thing like try to clean a windshield with a broken bottle? Also, Tom and Ray highlight an alarming new trend in public radio-canine relations, and we share a new battlefield fix to a door that won't close. All this, a new semi-automotive and possibly fully-bogus puzzler, and lots more, this week on Car Talk.
