I'm thinking of buying a 2002 WRX that has 91k on it but I want to know what the 100k maintenance is and how much it would cost. I've seen some posts saying that you don't need to do anything but just the basics like oil until 125k. But I've also seen others saying you need a lot done at 100k. I'm just curious on what would be a good idea to do at 100k.
