I made this cake for my twin boys 2nd birthday. It is a 13x9 standard cake with a 9" round cake, cut in half and placed on the ends. I used real toy cars on the cake (which also became a birthday present for the boys). I did find one at a g-sale and had my dh smash the front so it looked like it was wrecked. I used buttercream to decorate the entire cake.
