The doors can open revealing nice details. The wheels are made of rubber and they roll very smoothly, so be mindful of where and how you display it (don't have it roll off a table).
Particular to the tow truck model, the length is 12.75 inches from end to end and the height is 4.75 inches to the top of the box/container.
