Goodwill Warranty Criteria

GM gives us some latitude with goodwill warranty decisions but I'd like to hear what others look at with regard to this issue.
We struggle with the notion of rewarding customers with goodwill warranty when we review their history and all they see us for is warranty issues.
At the same time, we want to create a favorable impression of our service department and we certainly don't want them bad-mouthing us in our small town.
