I think you've got the only pro. If one does get one that far away, and I can't see any reason one couldn't find a good machine much closer, do just like Central WI farmer said and get pictures of every square inch. Find an independent mechanic to check it out. Even then it's a pig in the poke. Find someone on this forum who might live close enough to check it out, but I sure wouldn't just buy itI know some guys who have bought tractors sight unseen, thousands of miles away. How do you even know what you are getting? Pros and cons? I guess a pro would be a much wider selection of tractors.
As Tjim said, non powered stuff yes as long as you get lots of good pics. As for a tractor or something, unless it is a low hour newer one, absolutely positively not even on a rainy day ever To do so with something older could and very well would be courting total possible disaster. Once they have your money, no dealer is going to stand behind any older machine, you will be completely on your own if an unscrupulous salesman ( and yes they exist) feeds you a line of bullshit.It would be fairly safe to buy non-powered implements, like tillage equipment, right? I see quite a few plows and such that I would like to get. Not a lot of stuff for sale around here.
