This week on The Best of Car Talk, Matt needs a car that can handle his annual 100,000 mile commute, and no, we didn't add too many zeros there. Matt is looking for reliability and good gas mileage, but Tom and Ray think he should be a bit more self-centered, particularly on the body part that will be chained to the seat for all those miles. Elsewhere, Marc is wondering if add-ons like the "Crap-a-Chip" will really improve his SUV's horrible mileage. Also, Mary Anne's air conditioning is cooling her passengers but not herself; Chip is wondering what fried his van's exhaust manifold; and Tom and Ray's efforts to help Becky deal with a film on her windshield are derailed by the Car Talk Studio Pranks department. All this and more, this week on The Best of Car Talk.
