Two years ago I sold my vintage red GTS250. It was 8 years old, and had about 60,000 km on the clock. I hoped for $5000, then had it advertised at $4000 for several months, and finally sold it for $3500.
Yours has a much lower mileage, and if it is all standard you might get a better price, but don't be too optimistic.
Good luck. ...
