The Best of Car Talk is hosted by Tom and Ray Magliozzi, better known to their listeners as "Click and Clack, the Tappet Brothers" - monikers taken from the clickety-clack sound of aging automobiles. During the show, the brothers freely dispense expert car advice to callers in the broad accents of their native East Cambridge neighborhood. But the irreverent program is about much more than just automotive repair. "We know that the calls about car problems aren't our best calls, so our best calls had to be something else" says Tom. Whatever the call, Tom and Ray handle each with spirited comments and sound advice that listeners have grown to expect each week.
