Kestrel Take
An Outback that doesn't want you to know it's an Outback. Same platform, same CVT questions, same excellent all-weather manners, several thousand dollars cheaper because it isn't shaped like an adventure. Great value if the CVT checks out.
Known Issues for the 2018 Subaru Legacy

The dominant risk on any modern Subaru. Extended warranty coverage applied to earlier years; on a 2018 you are on your own past 60k/5 years.
Repair cost range: $4,000-$6,500
Subaru of this era ships a marginal battery and the modules draw more than it likes. Many owners are on their third battery.
