A functional pair of locking axles run about $2k. Armor loses some value after use, but even at 75% value it's still a good buy. If it's going up on Craigslist, I'd bump that up a little bit, unless you're looking for a quick sale. The rust is the only concern I would have, and even that isn't enough to deter me. The only reason I haven't jumped on it is because I'm trying to get out of debt.$4,370, actually. That's front and rear bumpers, sliders, and skid plate.
It's just really rusty. Trying to account for that. Although, I'm not really in touch with the 80 market these days. If you think that's stupid low, let me know. (sooner, rather than later!)
