Absolutely Useless #11

Maybe not completely useless, but useless enough that I couldn't file it anywhere else.

This guy has blended the unthinkable - A Smartank? Econo-tread? Smart-mobile?

I guess without an open field it wouldn't be as fun...

Still haven't had enough Smart madness? Well, then this should quench your need for more absolutely useless things to do to an econobox...
