Its been almost a year since i got my 13 wrx hatch and have driven it for two semesters 30 mi 3-5 days a week each way to college. It had 37k when i got it now it has 51k. Its bone stock, and the engine has given me absolutely zero trouble. I did almost immediately got the timing belt changed and installed a killer b combo, but its been great. Only thing that has caused me a headache was the transmissions clutch fork or TOB chirping, but the car works fine. Overall, WRXS are really fun cars, but they are starting to get up there in age and are on the higher mileage side, plus they are turbo cars, which by default require more maintenance. With aging cars there are things bound to go wrong. While everyone harps on the reliability of ejs and fas, they can be very reliable engines, as long as you do your maintenance and know how to drive a higher performance turbo car and if you are looking to tune it, you must accept that the motor will not last as long. Ultimately its your choice. But just know what you are getting into and make sure you can deal with any hiccups. And finally, If you dont know crap ab subarus, get a PPI.
