I assume you know these are grey market used tractors...right? Therefore they are not intended for sale in the US, and 'dealers' are really importers/resellers. If you didnt know that, please spend some time in the yanmar and grey market sections of this website educating yourself about the pros and cons of this approach. Let me offer my perspective:
Grey market tractors provide a real value for the right price, and the right buyer. When you buy one of these rigs you are on your own - you will have to search for parts yourself, and do repairs yourself. You may find a local shop willing to do some work if you provide parts, but that will be iffy - especially during the busy growing season. So if it is a comparably cheap tractor, and you are handy - it is a perfect match.
The problem I see is that these arent cheap tractors! Often they have been reconditioned (which makes them pretty) and therefore they are quite pricey. Often you will pay $8-10,000 for a reconditioned Yanmar/Iseki with a new loader. Why take this risk for that price when you can buy a new, warrantied Kubota L2600DT for $10,000 - maybe as low as $13000 with loader, low rate financing, dealer support, high resale...etc.
I dont want to 'poo poo' anyone's plans, but with each brand selling an economy tractor (Kubota L2600, L3000; Deere 790/990; NH TC30; Kioti 2554, etc) I dont see the value of 20 year old grey markets for 2/3 or more of the price.
