This week on Car Talk, Tara in Fremont, California, pays Tom and Ray a return visit. Last Fall, Tara was trying to decide whether to keep dating a guy who lived in a VW van. Now, she's decided that Van Man is Mr. Right-- so much so, that they're about to embark on a cross-country cruise. Do Tom and Ray have any sage advice, aside from duct-taping a few spare mechanics to the roof? Also, a family Volvo becomes a laugh riot as it loses its ability to stop, a college professor discovers the potentially stinky consequence of flunking students, and, if you're in Evanston, Wyoming, beware: a prank war is getting a touch out of hand. All this, and more, this week on Car Talk.
