Welcome to HQ. Shoot us some pics and a asking price. Might be able to help you out more. Some people over price what they have b/c most people do not know what a shee is all about.
Look for neglect like oil and water color. Bent, broken, frame and worn bearings. Bushings, and front-end parts look strait. Other typical signs of wear. Somethings are ok, as long as the price is in the right range.
