like everyone else i think you have to have a test drive and a good sit down and ask your self if you can afford maintaining either or. how often will you be driving it and what happens to it when your off overseas again? are you able to bring it with you in a hercules? that would be pretty cool if you could, whack a parachute on it.
i respect subies, they are great car to drive. i have a thing for the liberty sti's as repeated they are two very different cars.
