Politicians aren't the only ones in DC that come in just two types. Allen from Washington, DC is facing a dilemma regarding his local mechanics and humbly asks the boys a very profound question: When faced with a mechanic who is either honest and incompetent or one who is competent but crooked, how do you choose? Fortunately(or unfortunately?), Allen has come to the leading authorities on automotive incompetency. That, plus more calls and a new puzzler on this episode of the Best of Car Talk.
