Turbo subaru motors do not blow head gaskets whether 2.0L, 2.2L or 2.5L. A non-issue.
I'm with you there, but they do have added complexity due to the turbo and need to have been maintained properly with oil/filter changes. There's that pesky "banjo-bolt" screen that can plug and smoke the turbo bearings.
Like you say, $4K would be awesome, but I say best of luck with that in today's market.
