This week on Car Talk, Jill has noticed a raft of men picking their noses in their cars. Is this topic too juvenile and tasteless even for Tom and Ray? Are you kidding? Tune in as they dive deep to try to explain why a man’s car is his nostril's sanctuary. In matters a bit more serious, Paul’s car is smoking like a chimney,and he’s hoping to find the right additive cocktail that will get it through to spring; Bernie and Rollie’s test drive at a dealer ended with an encounter with a light pole, and now the dealer is trying to get them to pay for the damage; and is Jenny or her budding bryologist fiance right about her Civic’s starting problem? All this and lots more, this week on Car Talk.
