Shop the open market.
We went with Eagle Vision but you should shop them first.
IMHO you must get an exclusionary policy with consequential damage.
Exclusionary means they list what isn't covered if it isn't excluded it is covered.
Consequential means that if a covered item causes something else to be damaged that thing is covered also.
Our plan was a flat single fee of $5900 for a 5 year 40K miles exclusionary, contract that covers everything of importance and has consequential damage.
This is our second contract and the one carveout is that unless your up for fighting tooth and nail they aren't paying 100% of the cost. It turns out to be more like 80% coverage. What they do is not agree to the price the shop is quoting claiming it isn't "customary". You can fight it, or you can try to find a shop that will do it for their price, or you can pay the difference.
For our first contract we preferred to have our favorite shop do the work and pay the difference. We still came out ahead. We has a slide go bad and the inverter go bad and even with the 80% shenanigans we were in the black with the warranty.
If you are real luck you buy the warranty and nothing ever breaks ;-)
