I just read too many subaru forums and hear about a lot of cylinder 4 blown pistons and spun bearings, and blown 5 speed transmissions. Mostly just when you start pushing big power with poorly executed mods, or just beat on the car. Subaru did lose a class action suit on the cylinder 4 rod bearing though so they're covering them on an extended basis. I bought the car from a private party but my credit union gave a two year/20K mile powertrain warranty on it for cheap, couldn't say no. I have an intake and exhaust and a mild tune that I can uninstall if I have any issues. We'll see. You get too into the mods something will blow up anyway. My insurance on this car is right around $100/month. Not bad at all. I don't drive a ton and have a spotless record. I know they'll get ya for insurance on an STI to a whole other level though.
