That's an OK deal, but not fantastic. I have been passively "advertising" mine locally with a few more options and utility trailer for $13500 to selected folks I know, so I would say that for a real solid price it is about $500-1000 high but not too far off. As stated, used, low hour 2320's are hard to come by, so you are likely to see a broad variety of prices. One thing that affects price on this, and other, compact tractors is the current JD financing. JD has been offering 0% on certain models and for some who may have interest but do not want to pay an up-front lump sum cash, paying more for a new machine at 0% has some appeal. For this reason, low hour used machines have to show enough of a difference in price with still top-notch condition to merit much interest. I do not know how much that would be but for folks who do not mind paying cash and saving several thousand dollars to do so, this would be the way to go. As you likely know, a sub 100 hour machine in really good shape will last years and years. The 2320 is a really good little machine, perhaps the most solid tractor I have owned despite being the smallest.
