Are there first party extended warranties? I'm assuming the Subaru Gold mentioned above is?
There will be a Subaru Added Security (SAS) Gold plan available. No, I don't know what it'll cost (or what it'll REALLY cost), I'm not in the business office.
There's also a Silver and other level plans available. One of the things with these is that there are just so many variables, including mileage, coverage, deductibles, and length of contract, that the cost really DOES vary a lot. Then you add in the actual third party stuff like Resistal or Wheel & Tire coverage, it can get confusing. I know no one likes to spend time in the business office, but go in there with an open mind about coverage. These are ALL Eyesight vehicles, and while I hope we don't have the windshield issue we had in the '15's, they're still expensive to replace correctly.
Before you jump on me about insurance stuff and windshields, keep in mind that what's good in your state may not be good around the whole country, because individual state insurance laws vary.
