Do you trust the guy that has a product to sell, or do you trust the guy that bought that product and tells you of his experience with it?
If this sounds like a knock on the suppliers we depend on for our Ford parts, you're wrong.
This knock is on the Newbies who run straight to the suppliers with their questions, and buy the newest most modern gizmo that supplier has for sale.
Then when it doesn't meet their expectations, they belatedly come here to the Ford Barn.
That's not on the suppliers, their job is selling parts, not educating Newbies.
Suppliers don't argue, they tell the Newbie what he wants to hear.
I should define who I'm calling Newbies: A Newbie is anyone lacking hands-on experience in whatever.
The nickname is not a slur, it's just how it is.
Bottom line is, if you haven't the prior experience, ask someone who has.
