If you’ve never owned 4wd or awd, be aware that AWD will require extra attention from the owner about their tires. Subarus are notorious for being quite picky with mismatched tires; meaning, if you have a blow out, you’ll either have to get 4 new tires, or have the new tire shaved to match the others. You’ll also have to make sure you don’t have different brands/treads as well, this will also affect the drivetrain components and can lead to an expensive repair down the road.
