No, I'm not swapping out Tetanus, although this toy doesn't have any rust! (and doesn't cost near as much to operate!)
I'm not sure why the front tires are smaller?!? It was a christmas gift. It is one of those toys that you pull back and it winds a small gear and takes off when you let it go. It has some "real" springs under it, so I thought it would be funny to ramp it on one of my drafting triangles here at work. Mario did kick my trucks azz though!!!
