Judging by the way that the insurance company is handling the claim, and judging from the photos that i've seen, i'd almost say that it wouldn't be worth repairing/inspecting to make road legal again. Take a write-off settlement, and buy the car back. You can easily part it out and get a fair amount worth from everything. Just to give you a ball-park, when my wrx was written off, I had it up for a couple of weeks asking ~$4k (I think) for the whole thing, and I think I made just over that parting it all out. With a car like yours, i'm sure you'd be able to part it out for a good price. Plus you still have that WRX RA that you picked up in the late summer as well, right?
Oh, and if you do go with a part out, let me know as soon as you decide! I would definitely be interested in a few things!
