Im currently looking at a 2003 mazda 6s with 55k miles, its a manual, and when it first starts up theres a squeal, that sounds like a belt squealing, but it only lasts for about 5 seconds, the car is at a small used car dealership, so these arent quite the professionals like if you were buying it from a normal dealership, but when i asked what the problem was, one person said a belt the owner said it was the fly wheel, but nothing serious, i was wondering if anybody here has had this issue or would know what it really is, and how much trouble/ cost to fix? or is it just something thatll make a noise but not be harmful?
