I think you could get at least $3500 for your Viper. Last winter when I was still looking for a SX 600R, I found a few Vipers at a local Yamaha dealership.
They wanted $4800 for a standard Viper and they also had a Viper ER that they wanted $5300. Both were '03s. This past August, just before I bought my XC, the same dealer had an '04 Viper ER that they wanted $5800 for. To ask $3500-$4000 would not be out of line. You want to SELL your Viper, not GIVE IT AWAY!
I like the looks of the sled with the Boss seat. If I planned on keeping my XC for a long time, I would probably put a similar seat on it. The stock Polaris seat sucks! It makes it too hard to transition from sitting to standing, something that comes in handy when you come upon the unexpected big bump!
Hey BlueViper1, I like your brand choices! Gotta respect someone who is smart enough to own both a Yamaha and a Toyota! Tundras rock!
