A Mystery Wrapped In An Enigma

I am borrowing what I think were Churchill’s words to describe this Volkswagen seen at the NSW hot rod show. It seemed straightforward enough at first when I saw it across the hall, but closer examination left me puzzled.

The half-way nature of it is what is most puzzling. There is a killer paint job at the rear, and some dramatic black used on the front and the inside…but where are all the rest of the bits?

Is it a work in progress? Or a rod made for a division of motor sport that I have yet to encounter? Or an art installation that can be rolled in and out? Who would spend all that money to do all that work and to show it to all those people? In that state?

Answers in an envelope, please, and slip it under the door after midnight…
