My dad has 125k on a 2002 WRX without issue. I know that's a 2.0 and the head gasket problem is supposed to be mainly with the 2.5. I'm sure plenty of people get lots of miles out of them without issue, but in the grand scheme of things unless you need AWD there are better deals out there for 11 year old used vehicles that will be cheaper to live with.
