Here is my dilemma: Many of the used cars I have been test driving seem fine but when I stop at a stop light I notice they idol roughly or have a vibration sound coming from under the hood. The dealer sales person who is driving with me first tells me that I am imagining the sound and he does not hear anything. Then when pressed he said, well yes, I hear something but don't worry if it bothers you in the future the car is still under warranty, they will fix it.

But will they? It is not a repair of something that has broken down, but instead, it is a vibration sound, or a sense on my part that the idling is rough. What will they say if I complain about vibration sounds and try to get it fixed as part of the 36000 mile bumper to bumper warranty?

And pigs fly too! This is car salesman talk ,i.e. lies, that would make me run like crazy off that lot!!
