It really depends on a visual inspection and how much prior maintenance has been done before. A simple tune up may not be enough. You might need tires, brakes, shocks, bearings, all fluids and filters, battery and electrical systems parts, etc etc.. it just depends on what all those look like, and act together. And these are just scratching the surface. A qualified mechanic should be a first starting point. A good scan will also help to point out problems.
