My 2yo got this for Easter from my mother. We pulled it out of the box, and from the second it was together, he LOVED it.
He loves that the wheels move up and down, so he can drive over all sorts of bumpy surfaces! (He sets up his own obstacle courses, now!)
He like that he can put stuff in the crate on the back and tow it around, and he also takes the crate off and clips on other brand trailers, etc and tows those around.
In general, it's a great toy, with lots of possibilities, and promotes endless hours of imagination play which is SO important.
