I actually bought the truck for him, to help with training him . I make him wait (which is tough for him) and then tell him he can go get it. He is very very prey driven, and we've had problems with that instinct lately.
The bodies are real flimsy, and you can order additional bodies, but the parts underneath are tough, We've flipped it and ran into all sorts of stuff, and nothing broken yet. I wish it were a little faster, Mowgli can catch up to it with no problem, he grabs the tires and throws it in the air and flips it, like it is some kind of prey.
What is kinda funny, is the our two Newfs will chase and bark at it , but they will NOT touch it, and they sure don't want it touching them. Mowglie is just the opposite.. kill kill kill
