>This smells like a class action suit...
Nothing wrong with that... the sludge problems are well documented.
Clogged screens, PSV issues, etc. Lots of motors dying. If Saab is not
treating people right in the repair department, a suit is reasonable.
I know they are fixing some cars, but I think they (GM) are insisting
on lots of oil change documentation from anyone before they honor the
claim - and since it's a known problem, that would be unreasonable. If
they are, they deserve to be sued.
