It's an interesting discussion. I bought an MCX270HP Nytro a couple of years ago for $11,500. Probably had $25,000-$30,000 in it. I really like riding that sled. Had one $40 voltage regulator and one $70 belt blow in 2 light years of riding it. Lots of fun in deep snow. I have a Cat 1100T that I have been the "fool" on and have a metric f ton of money in it. It's a better sled than the Nytro but not 3 times as good. I wonder about all the guys getting Vipers and doing the same thing. I saw the Robertson Yamaha quote of $33,000 for a long track higher HP Viper and that didn't include any of the LW parts or suspension a 4 stroke sled needs to be really fun to ride. Those are going to be the next money pit sled.
So back on topic I would put $12,500 on it, and be ready to sell it a little cheaper. It really is a beautiful sled and someone is going to appreciate all the detail work you have put into it. Also, see if you can find a way to sell it into Russia. Those guys are going nuts sledding and have tons of cash to actually blow. Would be more popular on the Eastern Front if you had powder coated everything Red though.
