My opinion is that 6k for a 750 that has obviously been repainted is to much $$$ . As soon as I pay off my '01 900SS in a few weeks, and get my hands on the title, I will only be looking for about $6500. And thats with Arrow exhaust, ZG screen, a couple other little aftermarket goodies, and absolutly no damage whatsoever!
Good luck, what ever you chose to do. But do a little more research. NADA price guide has low retail as $4300 and average retail as $5500. Hope this helps in your decision.
