The Volvo VN-780 model at 1/32 scale by NewRay measures about 11 inches long by about 3 inches wide by about 5 inches high (to the top of the cab). The main cab is made of diecast metal while the details are made of plastic. It has very nice details such as separate clear plastic headlights and accurate grills. The coloring is done is high gloss finish with accurate markings and branding.
The wheels are free rolling and made of rubber. The rolling motion is very smooth so be mindful of where you display it (or chuck the wheels).
The doors can open revealing nice interior details such as accurate seats, steering wheel, instrument panel and gear shifting lever.
These models are really not toys. They are made to look realistic and mainly for display purposes, because of this, they have small parts that are very fragile. These will not survive a spin around the sandbox.
