I think the pricing is right on.
The rig is rare, something like one of 2250 ever produced. It is narrow and light, a very desirable combination for lots of folks. Add to that the the rig looks to be in VERY good shape and ready to go, it all adds up to a rig that SHOULD bring top of the market.
When folks ask me about my TM and ask if I'd sell it (which is sort of silly, I'll sell about anything...) they usually have no point of reference to equate my asking price to anything they are familiar with. I usually point out that a person can easily spend well over $10K on a snowmobile these days and not have anything close to a snowcat.
While many folks here have a point of reference, I have not heard of anyone that has actually laid eyes on this rig and/or are looking to buy. We are more appraisers than buyers. The buyer of this rig will probably develop an emotional attachment to it prior to the purchase and that will, more than anything dictate the price paid. Isn't that, at some level, why most of us have cats? The buyer of this rig will WANT it, and probably not really NEED it.
In our neck of the woods, there are second (or third or fourth) homeowners who have lots more disposable income than I will ever have and have spent more than the asking price of this rig on a side by side and accessories to try to get around in the snow. They would have spent their money much more wisely on this machine at the full asking price than buying what they have. AND, compare what that dolled up side by side is going to be worth in 3 years compared to this rig. There is no comparison, other than what is paid.
I think that what someone else paid for something similar or what some else is asking for their stuff has very little to do with what something is worth, especially in a "don't have to sell" situation.
Great looking rig, GLWS and I bet the next owner will be happy with the purchase.
