Dave,
I paid $27,000 for my 6520 back in 2007. Since you didn't give us your purchase price, I can only go on my sales price. I am thinking I would try to get $25,000 for mine, if it had only 200 hours. So I suggest trying somewhere between $25,000 and $26,000. Now my question..........................................why sale an awesome tractor?
hugs, Brandi
