So, I'm thinking of buying a used WRX. I've always been a streetbike guy, but now I have a family and had to sell all my toys. My only problem is I really don't know where to start when it comes to working on these things. I think I've got a bone stock 02 w/ 58K miles on it pretty much purchased. Good starting place/bad starting place? And where do I go from there, w/out the obvious bolt-ons?

Thanks!
