Replying to Subaru Talk. Advice?

So my ford explorer has a full page list of what needs to be repaired, serviced, or completely replaced. its an 01, but its a rebuilt with a salvage title, so i cant get much, if any trade in value for it.

thinking it might be time to get a subaru. i was thinking something around 1998-2002. My real question is how long do subarus last? i have heard 200k, 300k, and even more in some cases.  Most the cars in my price range have somewhere around 100,000-150,000 miles on them. would it be a risk to get a car with that high of miles? or is that average for a ten year old subaru?

also since i'm moving to canada for school i'll be driving back to spokane (3 hr's) once a month or so i would imagine. besides that its just to the mountain and to school. since its mostly going to be in town driving i dont think i will put many miles on it.

would buying a 150,000k subaru be a good investment or a bad decision?
