FujimiBlade Runner: Spinner Car | Model Kit | | Plastic | 1/24

what is the actual dimensions of the finished model (not the box) because saying 1/24 scale of a non existant fictional vehicle is a little vague?

does it come in all the colors shown like the police lights etc or do you have paint everything?

Could one eat it? (if so inclined)

Is this blade runner spinner pre-built and ready to display or does it have to be built by the user?
