The Mercedes-Benz Actros at 1/32 scale by Welly measures about 7.25 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 extended cab and details such as mirrors, exhaust pipes, steps, gas tanks, etc, are made of plastic with chrome finish. It has very nice details such as separate clear plastic headlights. 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). It has interior details such as accurate seats, steering wheel and instrument panel. 
 
This is not a toy, it is a display model recommended for 14 and older.
