If you want to check out the pricing of thousands of sleds, check out the White Star Snowmobile Auction price reports. I believe the address is www.snowmobileauction.com You can access several months of auctions and get a general idea of what different machines sell for. As a general rule when you get into the older machines, condition is everything. For my money I would save a little more and look into a Yamaha from the mid to late 80's. As a frequent "shade tree" mechanic on my friends sleds it seems that the older machines all have needs and you can easily spend twice what you are looking to spend to keep them running.
