Look, if you buy it, just have it fluid filmed very well every late fall, around thanksgiving. Find a place you trust and make sure they do it inside and out. Plus they'll do bottom of floors, suspension, etc. in the spring, bring it to a self use car wash and pressure wash all that crap inside and outside the frame. Next year: Repeat. If it has SKIS (Grey Key) don't worry so much about a kill switch as this is basically the same thing. If it doesn't, yeah, a kill switch would be a good idea.
Whatever you do, don't do any rubberized undercoating. If you find someone who does a good job with fluid film (just the clear, not the black, don't want to hide anything) this is probably the best you can do. I've been doing it on several of my vehicles, one for 15 years and its been holding up very well. If you have a place and can do some of this yourself, you can spray fluid film inside the doors and pretty much all the little places that a garage won't do.
She looks good. The gears suck. Mine has 3.73 with 31s and I wish I had at least 4.10s. You can live with it for a daily, especially if it's an auto (I didn't look).
Good luck, let us know what you decide. She looks good!
Edit: I see it's a manual. Still, if it's mainly a street rig, I don't think you'll have any issues. As for light off roading, I'm not an expert, but the tcase should suck up alot of the crappy gearing with the 2:1 underdrive. If you're rock crawling, that's a whole 'nother story tho....
