I was on here for a few months prior to pulling the trigger on my first Subie purchase as well. It's a great way to hear all the good and the bad. I live in Portland, where you'd swear Subaru was giving out some special deal here.
They are not, think there's an up-charge here.
Anyone and almost everyone I have talked to can calm your nerves on the reliability factor. I came from having Hondas most of my life that were always "gas and go." I am anticipating it'll be the same here. And 23K miles in, no issues yet. And the gas mileage... I have had mine loaded up with gear, roof box, and a two bike hitch mount, going 75mph on the highway and still averaging in 29mpg. Hope that helps, Cheers.
