Non turbo subarus are pretty tough things as long as they are maintained, just wear and tear stuff really, just make sure everything works as it should, belts and plugs have been changed as well as the oil, if it has hi lo selector make sure it works etc...
And most of all enjoy!
Only thing with low mileage is make sure the tyres aren't also 8 years old, old rubber isn't good (which is why condoms have sell-by dates)
