I have this warranty package on my 2006 Pete. Until Dec of this year it covers turbo, injectors, pretty much everything. After that, I have another year of basic engine/powertrain, although I can opt back in to the comprehensive. The plus to the Premium 2000 warranty is they don't make you go to specific shops. Any qualified shop will do. I haven't had to use it yet, so I honestly don't know how good or bad they are, but the way I see it, even a bad warranty is better than no warranty.
A warranty is a strange thing... you buy it hoping you'll never have to use it.
