My 05 has 25K, so I would not be concerned with the milage. Turbo torch has a good point with the price of a new one. If you like the color of the 05 use the price of a new one and try to negotiate the price down. Ask the owner for the service records, take a look at the condition of the tires, rubber if needed to be replaced will cost a couple hundred. Brake pad wear, rotor condition, chain and sprockets are all things that may need attention. You did not mention any mods, but if the bike has had some $ spent on things like exhaust, power commander, wheels or bling, the asking price may be a little more in line with the market. If you have anyone from the org near you ask them if they would take a look at it with you and give you their opinion. Just my .02
