well heres my story i got my p7 impreza l wagon 2.2 auto with 113k for 3g's it booked for 6ish at the time, ive put about 2 g's into it and it looks like this now
its got an impreza sti v5 bumper grill, jdm fogs, sti badge full carbon fiber hood, lowered 2 inches on h&r race springs with a cold air intake enclosure and an apexi n1 catback...i also have gunmetal wrx wheels wrapped in pirelli p zeros....all of these modes total about 3 g's, 2 g's were cosmetic
so ide say depending on the mileage its an alright deal, when i got mine it was mint aside from the front bumper which was kinda crappy.
