I didn't break any parts while building. I use nippers to cut the pieces off the trees. The parts are to scale so they are thin. As I have said before really only had a problem with the 2 part front and rear nerf bars. The rear was tough but the front was much worse. I had a heck of a time getting it lined up and stuck just where I wanted it. The one stupid error I made was to put the gold stripe on without taping the hood and nose together before doing the decal. I have the piece on the nose a little off center. It was stupid and I know better, Been building models for over 50 years and I still do stupid stuff like that.
