+1 regarding "maintenance being the whole thing" with these cars.
I believe people who maintain 'em keep 'em. The ones which wash up on the auction house shores have been sieved and sorted so you're likely to get a rattly one.
I had a '95 Legacy (2.2l-ran like a watch). Subaru weakened the 2.2 to make it a 2.5 and the used examples I've seen did not impress me. They seem to get rod knock and they leak.
Be very careful (no drama-just fact)
