This week on the Best of Car Talk, Erin's roommate doesn't drive her old car but won't get rid of it, and Erin is tired of having to move it every day. Is Erin's best solution philosophical or conflagratory? Elsewhere, Nathaniel's attempt to show off his Saab to his future in-laws went downhill, literally, when it rolled down their driveway on its own. Also, Dee's truck sounds like singing dogs; Norm wants to know how to get his Stanza running after storing it over the winter, but will first have to incur Tommy's wrath over a sore knee; and Nancy wants to convince her husband that his Acura can live without a bra. All this, plus Tom and Ray's brilliant new "do whatever you want" strategy, and more, this week on The Best of Car Talk.
