Received model 42231 yesterday, finished it this morning. Took a few pictures of it side-by-side with the earlier model 42111 for those who are curious. What's my opinion of the new one? It has some new parts (some which I think might be from Bionicle), mostly stickers except printed on the front grille surrounding area. It's sturdier than the first version, looks blockier in most places, better on the front. Wheels feel small, the A, C and B pillars are not as flimsy as in the first release...
