Looks like a decent pick-up..
Couple things to consider with regard to a warranty. Do you have previous maintenance history on the car? Will you yourself be modding it? Will you personally be doing the regular servicing- oil changes, gear oil, little stuff, or can you do these things? Is your local Subaru dealership mod friendly? Do you have Subaru specific shops/tuners in your area?
If its been taken care of and had regular servicing, if it wasn't modded past stg2 and if you'll take great care of it, then my opinion is no warranty needed. Plus its already been modded to some point so you have to wonder if it would be denied a claim should something come up.
Worst case, turbo goes and takes motor with it. That's unlikely to happen if the oil was changed and topped off when needed though.
