Hey, look at this. Apparently, there's a 1/24 scale model of the Prius being released in another month or so.
Plastic models are so 1960. Paper - now that's a modeling medium with panache. See my post of January 2009: http://priuschat.com/forums/gen-ii-prius-main-forum/12653-prius-paper-model.html#post769471 And that thread contains, in Post #8, the pdf file for printing the model. Post #9 is the pdf of instructions in English. All you need are sharp scissors, Aleen's white craft glue, a straightedge and dead ballpoint pen for scoring folds, and the kitchen table with no distractions for a couple of hours.
