So I am not entirely certain on this, however Subaru of Sonora Subaru of Sonora | New 2021 & Used Subaru Dealership | Sonora, CA, I dont think that they are part of any large dealer groups based on the fact that they offer a 25 year power train warranty on all of their new cars... The downside is that you would have to drive to Sonora CA, to have any warranty work done. Not a bad deal sense Sonora is a really cool place to hang out.I did a google search for "best California Subaru dealership" and it pointed me back to several old threads right here. After browsing those threads there's no clear consensus and the focus is mainly on pricing, but there is a common thread that there are two or three big "auto groups" that own multiple Subaru dealerships and they are generally unsavory and do a form of price-fixing. They tend to hide the fact that they're all part of these giant auto groups. Seems that there are very few independent dealerships left.
