IMO - Do the deal before he realizes he will be auctioning the truck too because he doesn't want to take it to Florida with him. This is assuming you don't really want the truck. Wheel Horse makes beastly tractors that are strong and reliable. I don't know the D250 specifically but am generalizing on the brand. My neighbor has a Wheel Horse and can get most parts still (although it rarely needs anything other than gas & oil and sometimes a belt). There is always this forum where you can get, or someone will get, parts (new or used).
