This week on The Best of Car Talk, Melissa Petersen returns with another helpful critique. But how can Tom and Ray be geeks and hippies at the same time? Elsewhere, Quentin can't decide whether to restore his grandfather's Dodge Dart Swinger (the most inaccurately named car ever?), or re-gift it to the nearest crusher. Also, Moon's trip to the Grand Canyon was marked by an argument with his wife over air conditioning; Bernadette is considering a career change from one non-profit to another by becoming a mechanic; and should Diane add a paint overcoat to her daughter's Jetta, or is this (yet another) dealer scam? All this and more, this week on The Best of Car Talk.
