If you gave this as a Christmas or Birthday present, you would need nothing else to Complete it (except normal modelling tools, Screwdriver, Modelling knife etc)
You may like to paint the body shell though. It is supplied as a clear shell, with decals. The painting can be as complex as you wish, but the pictures above show this model simply painted in White with decals applied
