Good, someone mentioned the tires! Tires more than 6 years old are a no no even on cages, much less motorcycles where you only have 2 of them keeping you upright! You certainly have a tough decision as IMHO both are worthy of consideration. I agree with Brian, start at an offer of $2000 and negotiate from there. You should be able to pick up either for less than $3000, just bring the cash with you as money talks, bull crap walks!
When it comes to resale, bling adds very little to the value of a bike. If anything it personalizes a bike and the buyer might not have the same personality! This was brought out in a recent episode of Pawn Stars where a bike (yes, a Harley) was brought in with a red paint with pink flames and Big Hoss's argument was that there wasn't a big market for bikes with pink flames and that he would have to repaint the bike to make it salable which brought the offering price down a couple of thousand dollars. The same is true of lights and chrome doo dads. Although they cost to buy, they do not necessarily make the bike any more desirable or run any better...
