It may be very well be worth it as far as the service you get out of it, but it is 9 years old now, and bikes don't hold their value well, especially if they are not a well known name brand. Not saying it's not worth it, but that is top dollar. It would need to be in excellent mechanical condition to be worth that much. I would likely buy it if a good going over didn't turn up anything bad, because I want a freeway legal scooter.
I won't spend more on a bike than I think it's worth, but if it's a good deal, I don't seem to have a problem buying bikes I don't need.
