Tom and Ray Magliozzi

Tom died on November 3, 2014, aged 77, in Belmont, Massachusetts, of complications from Alzheimer's disease.

In January 1987, Susan Stamberg of Weekend Edition on NPR asked the two brothers to contribute weekly to her program. Nine months later, Car Talk premiered as an independent NPR program. In 1992, Tom and Ray won a Peabody Award for Car Talk for "distinguished achievement and meritorious public service". Tom and Ray continued to work in their repair garage while they produced Car Talk. On June 8, 2012, it was announced that Car Talk would stop producing new episodes in September 2012, though NPR would continue airing reruns of the show.

Tom and Ray both appeared in the Pixar films Cars (2006) and Cars 3 (2017). (Tom's role in the third film was accomplished through archival recordings, as it was produced after his death, while Ray reprised his role despite his retirement in 2012.) They played the owners of Rust-eze who discovered Lightning McQueen and gave him his first big break. Tom appeared as a 1963 Dodge Dart convertible, a reference to a car that he owned for many years and often mentioned on Car Talk. Ray appeared as a 1964 Dodge A100 van. In both films, they admonished: "Don't drive like my brother", the catchphrase from the close of their radio show.

The Magliozzi brothers also appeared in the sitcom Sabrina the Teenage Witch in an episode called "Driving Mr. Goodman" which aired on May 3, 2002. Sabrina calls them on a magical car radio for car advice. In the same year they appeared in the PBS Kids show Arthur episode called "Pick a Car, Any Car" which aired on November 25, 2002. Arthur calls them with a question about the family car, which would have been hauled away by the local mechanic without their help. The answer turns out to be a baby rattle lodged in the car's tailpipe. In 2008, the brothers starred in their own PBS animated series Click and Clack's As the Wrench Turns, playing fictionalized versions of themselves. They also hosted an episode of the PBS show NOVA entitled "The Car of the Future". Ray did radio and TV ads for eBay Motors in 2022.

In addition to the radio show, Tom wrote for CarTalk.com and ran his own consulting business. In 1999, the brothers returned to MIT to deliver a joint commencement speech to the graduates.

In 1989, the brothers started a newspaper column Click and Clack Talk Cars which, like the radio show, mixed serious advice with humor. King Features distributes the column. Ray continued to write the column, retitled Car Talk, after his brother's death in 2014, knowing he would have wanted the advice and humor to continue.

Ray taught science in Bennington, Vermont, for a few years before returning to Cambridge in 1973. He and Tom then opened a do-it-yourself repair shop named Hacker's Haven. The shop rented space and equipment to people who were trying to fix their own cars, but it was not profitable. Nevertheless, the two enjoyed the experience and were invited in 1977 to be part of a panel of automotive experts on Boston's National Public Radio affiliate WBUR-FM. Subsequently, the brothers converted the shop into a standard auto-repair shop named the Good News Garage.

Thomas Louis Magliozzi (June 28, 1937 – November 3, 2014) and his brother Raymond Francis Magliozzi (born March 30, 1949) were the co-hosts of NPR's weekly radio show Car Talk, where they were known as "Click and Clack, the Tappet Brothers". Their show was honored with a Peabody Award in 1992.
