||In my part of the world (NJ/eastern PA) a rough running (some rust, a few dents, cracked seat, no working lights, no major leaks) 318 is worth around $1000. A nice condition machine can easily sell for up to $2000. One with less than 500 hours can bring $2500. If it has a front plow, add $400, a rear 3 point hitch, add another $400, a rear PTO, add another $400, a single stage snowblower, add $350, or a 2 stage snowblower add $1000. A mechanical drive rear tiller add $400, a hydraulic drive tiller, add $750. The prices for the attachments are all assuming that they are in very good condition (can still show some rust and wear, but not beat up) and operate. These machines are getting old, and have declined some in price during the last couple of years, but are still sought after. At the time they were built, there was nothing better on the market and it is hard to find machines even today that can do what a 318 would do.
||I bought one last summer with 680 hours with a Snow Plow for $2300 and a rather beat up 214 with a snow blower in trade. The 214 needed some work, but I would have probably been better off to keep it and sell it myself, but I think I got a pretty good deal. The one I bought has very good tires, perfect seat, no rust and runs great. I can't believe how good it is at pushing snow and ice, and it is great for mowing.
