that's right around the time foresters went from EJ to FB so that will make a difference.
EJ - plan on a full timing kit soon. (just the belt is not enough). timing belt is 8 years old now and entering timing change interval by age. Don't pay premium price for a cheeseball timing belt only job.
If an FB engine: keep an eye out for oil consumption related info
also if an FB engine, check to see if they have similar serpentine pulley bearing failures like the H6 EZ engines do. they fail all the time at seemingly random mileages - i've seen them fail at 30k and last until 150k. i consider them 60k replacement items, that catches most of them. they're also super easy - $20 for 2 bearings and it takes well under and hour to tap them in and out so it's not a big deal. the FB belt routing looks suspiciously similar to he EZ/H6 engines so I'd guess they're going to fare similarly to those rather than other subaru platforms that never had this issue.
that being said - maybe the redesign has helped this issue...
otherwise just standard parts, inspection, axle boots, rust, fluid changes/history/maintenance.
