Well maybe not a full size one, but this link has all sorts of Copens and Daihatsu vehicles to make: http://www.daihatsu-aichi.co.jp/fun/paper_craft.html Here's my quick effort, not sure whether to attach the roof though...
That is brilliant I work with children with emotional and behavioural problems and my most challenging boys love things like papercraft. I can get a new UK production line going immediately I'm very impressed with your effort Your Majesty - I'd leave the roof off!
Ideal Copen: Free (Your Majesty), rattle-free (Old Badger), made in the UK (ClareL) inexpensive and rust-free forever...
Unfortunately main link won't work. managed to download one of the attachments but fat fingers and small model do not go together. Might try and print t on my A3 card (and get a bigger model)
