And you are one of them.
Truth!
And I think a lot of it has to do with the age of the car and the experience of its owners.
I am also a member of a couple of G6 forums.
Some of the most complex topics I've seen over there are almost mundane, compared to what we regularly see on our forums.
Which helps not a bit, when I try to do something with my G6 and nobody knows how.
The one standout is a guy who has an Alero (not even a G6) who has swapped an F40 in, in place of the automatic.
Regarding the Mustang forum... I have heard that the Corvette forums are even worse.
NONE of those guys will get their hands dirty. They'd rather pay someone else.
