I agree you should check…
I agree you should check fluid levels and such until you know you're used vehicle. You need to also do research as with subarus some years have well known issues like head gasket issues. That's what happens when you try new things like lighter oils. You should understand who buys different the brand of vehicle too. Subaru owners in Herbert don't like paved roads and will only sell/ trade thier vehicles after it bring pried from thier child dead hands. They, for the most part, are not chasing the newest shiny (button).
What find very bad about the situation is he got an outback for $4k from a non-subaru dealer (they make you belive it was a subaru dealer unless you read the article). So many red flags and why i trust subaru dealers over other car dealers (definitely some exceptions to that). They know one you go subaru you don't go back. They know they will get your repeat business.
