Case 2590 tractor in good working condition.

My uncle is thinking about selling his 2590. Is anyone looking for one and how much would you be willing to pay. My uncle doesn't have a set price on it so you the buyer can set the price. It has a little less then 6000 hours, power shift, 2 hydraulics, 1000 pto, 3 point hitch, all 4 matched set of 20.8 x 38 Firestone radials at 50% or better. The motor runs great and everything works as it should except the ac is not working, might need a new clutch on the compressor. The duals are not on the tractor now, the dual hub is the same as the inside one. The front weights and bracket do not go with. Would trade for a good JD 4020 with power shift. Message me if you have any interest.
