Wheel Birthday Cake Father In-laws 50th Birthday Cake?

Father In-laws 50th Birthday Cake? - wheel birthday cake

We are planning a party for my father and I take care of the cake. I was originally on a cake from the 50th, but do you think I could find a model for him? So my husband suggested that we make as a cake of your car, an excellent idea, because he loves his car, but I do not know, trying on ideas that form and manner of sweets and biscuits, I make the wheels and what can I do for Windows. It has a beige square. Ideas?
