What do you do with the leftover parts when you can't build fighter planes anymore?

looks like a go-cart...

Looks like the car in the movie Brazil

looks like just the the thing for picking up a 6 pack and some chips.

Isn't this a Heinkel?
And it was the Dutch Guy's escape vehicle
in the 3rd Austin Powers movie?

and you can pick up the 6 pak and chips only if you use the optional roof rack!

The Heinkels I've seen look more like an Isetta. This one's a Messerschmidt.
