Sad news out of Boston today: Tom and Ray Magliozzi, better known as the Saturday morning radio mechanics on NPR's "Car Talk," are calling it quits, the Associated Press reports.

They show will continue to air in reruns, but after 25 years of giving useful and hilarious advice on car maintenance to callers with every manner of malfunction, no new episodes will be produced. Older brother Tom is 74 years old, while Ray is 63.

The show was first broadcast on WBUR in Boston in 1977. It's now the most popular program on NPR and is heard coast-to-coast.
