I hope no one takes any offense at this question, but I'm looking for ideas what I should expect as a discount from new for a well-maintained 1999 33D/SS Boomer (some warranty), with 50+ hours, and assorted implements, most of them little used (one somewhat damaged but useable). I'm thinking 20%, including the 5-6% tax associated with buying new. Am I being too unrealistic? This was an advertised tractor from a presumably motivated seller, interested in upgrading. I guess it comes down to, how much more am I willing to pay for new and how much risk I am willing to take on a used machine.
