In my humble experience, those newly replaced parts and painted tank scream "accident." If I was selling a bike that had never been down, I wouldn't put the money into making it look only slightly better. I could be wrong, but I wouldn't take the chance. For that price, I'd buy a Gen 2.
Secondly, be careful of people that have watched too many episodes of Fast and Loud, Pawn Stars and other shows that show negotiation and now they think they are professional wheeler-dealers. Up here in WA state it seems every time I talk to someone about a bike or car, they vastly over value their vehicle just to make you think you got a deal by letting you talk them down to a price they already arrived at before you answered the ad. I was selling a mint condition Honda Shadow 750 advertised for a VERY reasonable market value. The first guy hit me with $1.000. I had to bite my tongue not to tell him to get off my property. I politely explained that it was worth 2.5 times that in trade value and there were two dealerships in town that would pay it in cash within walking distance and that he would have to beak that price to make it worth it.
