My wife and I just sold her 2006 Subaru B9 Tribeca with 161k miles for $750. Valve cover gaskets needed replaced, head gaskets would be needed soon (slowly seeping), power steering pump was going out, needed struts, bushings…a lot of work, probably to the tune of $5k+. I was in the same boat…I didn’t want to dump that kind of money into it, to risk something else major going wrong with it. Not an 2.5i outback, but a comparable. Sold it to a Subaru h6 mechanic who did a lot of work with h6 outback’s who was going to fix it and give it to his sister in law. Was happy it’d get fixed and live on, car still had a lot of life left in it.
Bonne chance!
