Read the owners manual(s). There is much more to know about cars than used to be the case.
One thing that matters more in Subarus than in many other cars is to avoid having a tire that varies much in size from the others. For example, replacing a blown-out tire with a new one, while the other three have been worn. Even if the model and the nominal size of the new tire are the same as the other three, its larger diameter can damage the AWD system.
I, too, like a lot about Mazdas but I see far more Subarus here in Duluth, and the Mazdas I see often have a lot more rust than other cars of their age. The Subaru AWD system beat out Toyota’s and Honda’s in on-snow tests run by CR a couple years back.
