I'm looking at a 960, and I need some advice on a fair offer to make. It has straight tin, but poorly painted the wrong color. (entire tractor was repainted; wrong colors) No cracks in the block, radiator is full of clean anti-freeze, gas tank is clean inside, but it is leaking some gas. No PS, has two sets of remotes. Tires are less than 50%, very weather checked. I don't know how long it's been sitting in the shed, but the battery was dead. Gauges are good, except for ammeter. Seller said his Dad bought it 7 years ago for $3000. What's a fair offer to make once they get it running, if it runs good? Thanks for any advice.
