As more pieces of cards get folded, the vehicle looks more lie a Buffel and less like a paper circuit diagram.

Here it is nearly finished looking quite Buffelish

I have left the window frames off for now as I am going to try to put 'glass' in them. I think the contrasting materials will make it look better.

Some of the folds help the model along, while others didn't quite look right. A few dabs of my 'ol friend Timber Mate fills these in.
 
Next the vehicle heads off to the spray booth.
