Sophie Saint Louis, Missouri - 1991 Saab 900
Sophie thinks her car is laughing at her. She hears a noise that sounds like laughing, usually at low speed, when the car is in a lower gear and she has her foot on the gas. She thinks it’s coming from the trunk or back seat, but her mechanic could not find anything. Tom and Ray think it could be a stuck brake--she should get a mechanic to ride with her, and try to trace the noise while it’s happening.
