How warranties actually work.

[Trogdor]

There are some tricks we use in order to get you in to our dealership to do the work. For example, a disappearing deductible. The warranty company we use is CNA. They're a great warranty company and cover damn near everything. They're accepted by just about any shop out there. BUT, there's a $100 deductible... unless you come to us for the work. If you come to us then we cover your deductible.

Or what some dealers will do is sell you some POS warranty that no one else expect that dealership and very few others use. That way you can pretty much only use it there.
