I haven't driven Subies nearly as much as most of you here but I'm 4th owner of a 205,000 mile 03 WRX wagon and I'm sure the kid owner before me was not nice to it. He ran some Cobb bolt-on mods and tuning maps before he put it back to stock when I bought it. When I went to test drive, it was over a quart low on oil and black as tar. Today, it still has the original engine, turbo and accessories. I've not even had to charge the A/C system. It did need a radiator at 175k and the center diff at 199K both of which I found easy to change myself. Otherwise, I have few complaints other than typical vacuum hoses and such getting old and cracking.
