Not to play with, but as a garden ornament, for the reception hall or whatever. Then why can't a classic be made of concrete? And for convenience's sake, it does not have to be entirely in actual size.
Betonauto.nl makes scale models of concrete. Scale models of trucks. And the price / weight ratio is worth Olympic gold. They are available in concrete color, standard lacquered or in your company colors. A great idea right?
