1) The stock seats on these bikes blow. You will likely notice it on a ride lasting longer than a half hour. I got rid of mine, got a Mustang Wide touring seat and never looked back.
2) if the bike is an '08 with only 3800 miles, I'd want to know how long it has sat at a time and how the fuel was treated and how it was winterized if you live in cold weather.
3) You may need a new battery soon if it hasn't been hooked up to a tender. MC batteries usually last 4-5 years if they haven't been maintained.
4) Check the rubber for rot cracks.
Other than that, it sounds like a good deal; I assume it's all stock with the fuel/air/exhaust?
