Tom and Ray Magliozzi, the Peabody Award-winning hosts of Car Talk on NPR, are better known as "Click and Clack, the Tappet Brothers," taking their names from the clickety-clack sound made by aging autos. Tom and Ray dispense car advice in the accents of the tough East Cambridge neighborhood in which they grew up. Both are graduates of MIT.

In 1973, the brothers opened Hacker's Haven, a do-it-yourself garage in Cambridge, MA, which rented space and tools to clients fixing their own cars. But as hippies turned into yuppies and car repair became more complicated, Hacker's Haven became the Good News Garage, a conventional car-repair service.

In 1977, Tom accepted an invitation to the studios of WBUR in Boston to discuss car repair, along with other mechanics. When he was invited back the following week, he asked, "Can I bring my brother?" The Magliozzis were given their own weekly program, Car Talk, which soon attracted a large local following. Ten years later, in October 31, 1987, Car Talk premiered on NPR.

Now, Car Talk is heard each week by over 3 million listeners on over 600 public radio stations. It's also heard all over the globe via satellite, on commercial stations, and via the stations of Armed Forces Radio. Car Talk's podcast consistently ranks as one of iTunes' most popular, with over 1 million downloads a month, and growing!

Tom Magliozzi holds a doctorate in marketing and has taught at Boston and Suffolk Universities; he now runs his own consulting business. Ray Magliozzi is still at the Good News Garage. The brothers also produce "Click and Clack," a King Features Syndicate newspaper column which appears in over 330 newspapers, and an award-winning website, cartalk.com, which attracts more than 100,000 unique visitors per week.

Tom and Ray have partnered with Chronicle Books for a variety of projects, including the "Car Talk Puzzler Deck," the "Car Talk Road Trip Journal and Maintenance Log," a series of Car Talk Page-a-Day Calendars, and Ask Click and Clack: Answers from Car Talk, a collection of the best of the Car Talk newspaper columns.

Tom and Ray's most recent books are In Our Humble Opinion and A Haircut in Horsetown and Other Great Car Talk Puzzlers. Their most recent albums include "Field Guide to the North American Wacko," "Doesn't Anyone Screen These Calls?: Calls about Animals and Cars," "Maternal Combustion: Calls about Moms and Cars," "Born Not to Run: More Disrespectful Car Songs," "The Hatchback of Notre Dame: More Car Talk Classics," and "Car Talk Car Tunes: The Car Talk Compendium of Disrespectful Car Songs, Volume 1."

In the spring of 2008, Tom and Ray hosted "Car of the Future," on PBS's NOVA series. They launch their own weekly, animated sitcom, As the Wrench Turns, on PBS in the summer of 2008.

Car Talk is produced for NPR by Dewey, Cheetham & Howe and WBUR in Boston. For more information, call Doug Berman at 617.876.6632.
