This week on Car Talk, those famous last words, "Hey guys, watch this!" strike again. This time, the victim is Dan--or rather, the clutch in his wife's 2000 CRV. Maybe driving up Lombard Street in San Francisco wasn't such a great idea after all. Can Tom and Ray rescue Dan from the marital doghouse? Meanwhile in Kentucky, Molly wants to know if a quarter and a roll of tape is a magic fix for her broken windshield. Also, Stump the Chumps welcomes back Brad, the "walking talking environmental disaster", to find out if he fixed his oil leak. And don't miss the debate over the proper brownies-to-mechanic ratio, and stupidity comes to a college classroom--literally. All this and more, this week on Car Talk.
