i have thought about getting a second gen wrx now that they have come down in price. mileage to a certain extent doesn't bother me, just as long as its bone stock and never been messed with. "virgin". as i have looked that seems just as hard as finding a "virgin" 80s straight axle toyota 4x4, idealy fuel injected.
otherwise order up some cheap exhaust and intake, and find a decent tune and call it a day. thats basically what i did to my duramax was 4" out, a ported lbz turbo inlet pipe, swiss cheese stock airbox, and efi live and it puts down 430whp and a whopping 890ftlbs.
