After looking very close at the picture of the fiberglass property, I have come to the conclusion the small wheels may be geared for mechanical advantage but the sacrafice in appearance is too significant. Big wheels are much more of the good look of the concept than I first realized. Guessing, they look like 16". Come on guys, please hold on to 18" at minimum. Of course economy is important but to win the market you need an edge, and appearance is that edge that will spark public interest. Use Ulra-caps for extra boost to turn those big wheels.
Go GM go!
