This week on Car Talk, Santa comes through big-time for Tom and Ray in their never ending quest to escape difficult callers. They're now the proud owners of the Get Off the Phone Excuse Machine, and it's likely to get an early test, thanks to Nancy and the Tupperware-like noise coming from her Volvo. Elsewhere, desperate times call for wacko measures, as Jamie considers plugging a cracked head with oatmeal; Mark ponders giving his Suburban a full drive-train transplant into a new body; and Julie goes shopping for any car that can survive her husband's aversion to the emergency brake. And, Jan "The Waver" responds to her husband's concerns about her overly friendly driving style. All this, and lots more, this week on Car Talk.
