I considered one for my last tractor purchase. The depreciation on them is hard to square. Units are selling or 1/3 of the original price with only a few hundred hours on them.
That is what brought some interest, but at the same time there are no steals in farming. Although in the end it was largely technical. The M7 wasn't enough frame for my needs, but I didn't really need the HP of the M8 (which is actually a Versatile anyway). Other manufacturers offer models that more closely align with my requirements.
I'm not sure I'd call them cheap. They're in the same price range as all the other brands with used machines of similar spec, plus some premium for being barely used. I am not sure there is any real price advantage. Agricultural markets are pretty efficient.
That might on the surface sound contradictory with high depreciation as that means someone has to pay for an expensive new machine. But they are not really at odds with each other when you think about it.
