I just picked this up. It's fun. The tabbing together in truck is not hugely secure and satisfying, but doable. Apart from that, it's an enjoyable figure.
Has anyone else noticed how in step 30 of the instructions it looks like there's supposed to be two tabs on the top of the forearms for the roof to plug into? They seem to have disappeared on the toy itself. They're clearly visible on the cover image of the instructions and I just looked at the development images on king_samlock's Instagram and they're there. I'm guessing they may have found them too hard to align properly so they got rid of them.
