You could wait and hope for a lower price, but by then someone else might come in and buy the sled you are considering and you might be outta luck.
The salesman my parents always dealth with at the local Ford dealer had a sign on the wall of his office that said something like this, "The car you look at today and plan to buy tomorrow may be the car that someone else looked at yesterday and will buy today...".
Besides, at least if you buy it now you will have the chance to put some miles on it before you have to put it away for the summer. If you wait untill March you will have the agony of a new sled in the garage but not being able to ride it. Believe me, that makes for one loooooooong summer!
