If you know what it was and used to listen to Car Talk, this article is a must read.
It wasn't about cars. It was about life. It wasn't political. It was about cars. I didn't catch it every week, but if I was in the car or near a radio at 10 AM on a Saturday, I would listen. It was formulaic, comfortable, like visiting with friends.
It expressed my own love for automobiles and the cost, the frustration, and sometimes the blood it cost me to keep my relics on the road.
I miss the show and still think it was the best thing NPR ever aired. Here's one episode I picked at random.
