1st, let me say thank you to BELLATHEBALL for helping me with this cake; if she hadn't have figured out the dimensions, I don't know what I would have done. I got Mike McCarey's DVD on doing cars cakes and just went for it. If I wasn't doing a cake for 100 people, it would have been easy, but, because it was so big, it took forever to do. Chocolate cake covered in fondant & modeling chocolate. I now LOVE modeling chocolate. Oh, when I had to move the cake to the cake board; it split. I saved it, but, I was in tears first!!
