How can i find out how much an old snowmobile is worth?

[blue83ranger]

Does anyone know a site where i could look up how much a Mercury Lightning snowmobile is worth? It's either a '71 or '72. The kelly blue book only goes back in the '90's. and there's not much listed on ebay. thanks for any help.

I could go get some, but I can only send them straight to you.
