I don't get pissed
I get even!!
Really, it happens too often, post up a car issue, get a few suggestions and they never come back to say what fixed the issue, I personally think it's because they found they either caused the issue or it was something overlooked.
The more posts here that show a resolution the more times a Google-fu search brings them to
and reinforces the #1 mustang related website status.
(I made up that #1 status but we deserve it.)
