Did you buy the extended warranty at the dealership ?
Try contacting them; they might help out.
We spent $770 on a 3 year extended warranty for our then new 2000 Mazda from
www.warrantygold.com; I had read a few basic positives about them on the web, and they advertised heavily that they were "backed by a leading bank and no matter what happens, our warranty would be good, we've been in business for years" blah blah blah.
They're out of business and the warranty is useless.
Drain, meet $770.
