What I have done in the past when listing something is first see what others are selling/sold for, more important are the sold for ones as they give the most realistic price. I did this for an RV back in 2019/2020. Listed it at the end of the season and it sat on RVTrader until late May when started getting hits on it and sold it for asking price in June. Little did I know it would be a hot market or I would have listed it higher and it would have still sold.
When I started research for a larger tractor, I gave some thought on selling my B2410 after purchase, so looked at the auction sites and sure enough, my tractor with backhoe is selling pretty close to what I paid for it 20 years ago.
Your asking price is not unrealistic, but is what the market demands today. In a year or two it may be a very different story, but today is a Sellers Market, and those who hold out, usually get what they ask for.
I have an L4060 HSTC on order, and looking at used, if found, usually 2015 models, the prices are less than $5,000 different between used and what I am getting new for, and those are models without the rear remotes installed. Tack on 6% finance rates and the end result is a much higher purchase price for used, so for those who can wait, they go with new, but those who need it now are your bread and butter.
