Curb rash is just cosmetic. Lug nuts are a non issue. The one that's slightly bent is probably not worth using since it will be difficult to balance and even then, it's not good to run. Tires are basically useless since you're not supposed to be running tires that are worn differently on AWD vehicles. And having 2 fair condition STi BBSs prob won't help you unless you complete the set. If you already have a set, it might make for a good spare in case you end up damaging one. $100 is a very good price though, but for you, probably still not worth your time or money unless you plan on reselling.
