I have an 05 that was salvaged and now is rebuilt and it only had 5 miles on it when I got it. I bought it about 5 years ago. Only problem was melted plastic. If you want to keep the bike, dont let rebuilt scare you off, but you need to know more why it was salvaged. Any frame damage would make it useless.
Some deals out there to be had, but he is asking full price for his motor. My 1441 was around $6k to build.
