Repeated repair costs on a 10-year old car vs. higher capital
investment on newer car will make it a wash. I'd buy a 5-year old or
less Subaru for the kid. It's going to be more reliable and safer
(think air bags) for him. Plus, a 5-year old Subaru ain't going any
faster than a 10-year old if both have the same 4 cyl. engine.
As a DIYer, I much prefer cars with at least 80K miles, preferably at least
100K. At 50K miles it is hard to tell how they have been treated; at 100K it
is hard to hide. I get some great deals on cars that need things like timing
belt changes and axle replacements. Then I have a fresh timing belt / water
pump / front side seals and axles

My car now has over 230K miles, and my
daughter's '93 Honda is about 210K IIRC.
Only once in recent years have I let car lust interfere with my most
important guidelines: no trace of rust in the radiator and no sludge visible
through the oil filler cap. I bought a Nissan 300ZX that had radiator rust
and regretted it at leisure. At 150K miles the car was no longer worth the
trouble.
I am uncertain about the status of possible head gasket failure, though.
Obviously, if the car has signs of head gasket problems I won't buy it if
the seller isn't pricing accordingly. But I don't know how much of a job it
is on a Subie. On my Volvo the manifold nuts would have to be heated cherry
red to get them off, and even at that broken studs are reportedly common.
