This week on Car Talk, Howard needs to drive a mattress from Boston to “Hunga-Dunga”, and wants to know how to keep it from flying off the roof of his car. Tom and Ray know one method that won’t work, as evidenced by an ill-fated attempt to transport 18 sheets of plywood. Elsewhere, Tina just learned a scary and stinky lesson why you shouldn’t drive drive down a mountain in Neutral; Jerry is looking for an alternative to the “stick and ballet pose” method he’s using to get his convertible top to work; and, on Stump the Chumps, we find out if Elisa accepted her parents’ bribe, um we mean, “generous offer” to buy her a new car if she married her live-in boyfriend. And, by popular demand, aonother reading of the Melissa letter. All this and lots more, this week on Car Talk.
