For spares or repairs

Found this in my loft

I put batteries in and the wheels just kept spinning

I took the top of it hoping to spot something simple, truth is I haven't a clue what Iam doing and have ended up losing the screws which hold it together. The battery cover for the car is missing and I think the remote is missing it's aerial.

Someone put there may be able to get it working correctly or it may be useful for parts.
