Headgaskets are generally good on the XT Foresters. It's he valve covers that tend to leak.
A few things to check, although not necessarily horrible in the looking/buying stage, but to consider as what should be done in the near future:
-Timing belt, water pump, pulleys, and all other related parts replaced around 105k.
-Does it have factory catted up-pipe and EGT? If so, these tend to break apart and get sucked into the turbo.
-Has it had the banjo bolt filter/screens removed? These tend to clog and starve the turbo of oil.
These are a few if the biggie items on this. Other than that, just check for the basics as you would any other car.
