Pedal cars

I will be building a pedal car in the near future when I finish my mini tug boat at http://tinytugboat.blogspot.com/, and will use the plans I got from blue prints .com and there is some good prints to build a car at you will have to scale them up....

They charge for these Pedal-Car drawings - $4.95

I don't know weather there is more sheets, I am not associated with them and have not bought there plans. But feed back might be helpful.
