One of my favorite podcasts is the Car Talk Call of the week. These guys are the sponsors from the Cars movie, and also the hosts of the great show on NPR. The way that these guys are able to identify issues in cars is amazing. I especially love it when they have the caller make the noise that the car is making and they are able to identify it from that. Whenever I do that at a repair location, the workers there just roll their eyes and jack up the price on me.
