This week on Car Talk we take a walk down memory lane to remember Tom's 10-minute military career. Who knew his mouth would get him into trouble? Then it's off to Baton Rouge, where Sandra mistakenly put diesel fuel in her Honda Odyssey. And Natalie from Washington wrecked her dad's Chevy. Is there any way to get it fixed before dad gets back from a trip? Or should she enter the witness protection program? All that, plus a new puzzler from the luncheonette department, this week on Car Talk.
