This week on Car Talk, the solution to any Customer Service nightmare in one mantra, courtesy of Tom and Ray's cousin. It's "I'm in trouble, and I need your help." Could you refuse someone who came to you with that plea? Find out which of our callers may be putting it to the test. Also, remember Tara from last week? She was dating a guy who lives in a van and wanted to know if that alone should disqualify him. Well, we've got an update this week, straight from the van dweller's mouth--and he's also got a question she didn't get around to asking. Plus, is there such a thing as a "dignified" fart? All this, plus a new Puzzler from the Travel and Leisure series, and lots more, this week on Car Talk.
