Costs for new snowmobiles may seem high, especially to those of us who remember buying brand new sleds for $4-5,000 back in the mid-nineties, but you do have to keep the costs in perspective, and it isn't just snowmobiles that have gotten "expensive."
According to NADA a 600cc liquid cooled Indy XLT listed for just over $5,500 in 1996. Today's Viper lists for $12,800. That is a difference of $7,300, or an increase in cost of @ 132% over the 1996 XLT. By the same token, a plain Jane 1996 4wd Chevrolet Pickup truck went for around $15,000 in 1996. Today that base Chevy 4wd pickup lists for over $35,000. That is a difference of $20,000, or an increase in cost of @ 133% over the 1996 Chevy.
The numbers aren't exact, and lord knows that I am not great at math, so feel free to double check, but it looks to me like the costs of snowmobiles have simply kept pace with the costs of other "necessities" (LOL). Granted, back in the mid-nineties, there were entry level sleds that cost significantly less than the XLT (I bought two brand new 500cc fan-cooled Polaris Trails and a trailer for under $10,000 back then). Still, in theory, if you could afford a new sled back in 1996, you should be able to afford a new sled in 2018.
