John Smith called to say his car is making noise. He said he's heard the noise before, but can't remember when or where. His wife drives the car sometimes, but she doesn't drive as well as he does. The noise is coming from under the hood. He's still driving it, and it's not an emergency, but he wants someone to look at it. His car is black, unlike his other car which is red. There is no light on the dashboard, but he's sure something is wrong. He works days, but his wife can bring the car in. It should still be under warranty, but he is not sure. It doesn't matter, he wants to bring it in anyway. His dog's name is Fido.
