This dump truck of yours is a serious project (both time-consuming and expensive). My friend assembled a Ferrari, probably about a 70cm long car..
and me? I assembled this little one a few months ago (I chose a car, and I could have chosen to assemble an airplane or some construction machine).

There is a joke. "On the box it says - from 6 years (old), I put it together in 3 hours"🤣
