Sorry to hear of your loss. As far as the Subaru, maintain as any other vehicle like normal until about 80k-90k then sell it. We researched these pretty hard a couple years ago. Large echanical issues start going wrong in the 100k-120k mile range it appears. Can't tell you how many of those we found in the 100k-150k mile range that either had a new engine and/or transmission or was sitting broke down that needed a new engine and/or transmission. Unless the 25' is a completely new mechanical platform, those findings were pretty consistent with the 2015 to 2021 models.
