Here are some simple toy cars and trucks I made for my four year old son. Very simple to make and I got the template from ToymakingPlans.com. I like the site but the plans seem rather expensive to me. The templates I downloaded are very simple and free. I think anyone could have drawn these without much trouble. You could really just take a picture of any car or truck and trace it. You can then figure out which items on those pics you would like to cut out or make small pieces to glue on. Not very difficult. I used my bandsaw for the out line then a disc sander to finish it up. I then used a scrollsaw for the windows.
