Hey topher long time no speak buddy,
Checked your pics and it looks like a good 9 bar the arches, it usually starts inside/out on the civics, would maybe need one arch cut out and replaced but one is salvageable
Other than that i think its a top car at a bargain price and even with the arches needing a bit of work so what? get them fixed and you would make your money back no problemo
Best of luck with the sale and hope it goes to someone who is going to fix the rust issues on it...
Take care chief
